    • An arm head includes an end portion to which a retainer is pivotally coupled and a surface covered by a coating. The end portion includes a coupling bore. The coupling bore includes an open end. First and second surfaces of the arm head form an annular recess around the open end that extends continuously from the open end. The radial outer surface extends outward in a radial direction from the annular recess. The first surface extends outward in the radial direction from the open end. The first surface is located inward in an axial direction of the coupling bore from the radial outer surface. The second surface extends from the first surface to the radial outer surface at an angle less than 180° with respect to the first surface.

    • A humidity-sensitive porous layer (13) of a humidity-sensitive element section (3) of a humidity sensor (1) is formed of a crystalline phase oxide grains such as Al2O3—SnO2—TiO2 and of a glass phase such as silicate glass covering the crystalline phase. The glass phase contains an alkali metal oxide and/or alkaline earth metal oxide such as Li2O. The humidity sensitive porous layer (13) assumes a skeletal structure that is formed of crystalline phase oxide grains covered or coated with the glass phase. A heater (17) of the humidity sensor is controlled to heat the humidity-sensitive element section (3) at a temperature ranging from 500° C. to 800° C. so as to clean off the humidity-sensitive element section while an internal combustion engine is running and exhausting fouling substances. Measurement of Humidity in an exhaust gas exhausted from an exhaust gas purifying apparatus of an internal combustion engine is carried out by using the humidity sensor (1), so long as the exhaust gas temperature does not exceed 100° C. regardless of whether or not the engine is running.

    • A detecting-element assembly (40) is configured such that a piezoelectric element (51) is housed in a casing body portion (43) of a casing (42), and is attached to a housing portion (22) of a flow path formation member (20) via a flange portion (41). Therefore, the path between the piezoelectric element (51) and the position of attachment of the detecting-element assembly (40) is elongated, whereby ultrasonic waves which leak into the interior of the detecting-element assembly (40) from the piezoelectric element (51) become unlikely to reflectively return from a joint. Thus, the influence of, for example, noise stemming from reflected waves is reduced, thereby enhancing the accuracy of detection. An average clearance of 1 millimeter or more is provided along the outer circumferential surface of the casing body portion (43) of the detecting-element assembly (40), whereby a problem of collected foreign matter is unlikely to occur.

    • A gas concentration sensor includes a measurement chamber for measuring a concentration of a specific gas component in a gas under measurement; an inflow path for allowing inflow of the gas under measurement thereinto and an outflow path for allowing outflow of the gas under measurement therefrom; a reflection wall for reflecting an acoustic wave; and an acoustic wave transmitting-receiving element having a transmitting-receiving surface adapted to transmit an acoustic wave toward the reflection wall and receive an acoustic wave reflected from the reflection wall. The concentration of the specific gas in the gas under measurement is detected on the basis of a propagation time between transmission of the acoustic wave and reception of the reflected acoustic wave. When a predetermined member having the sensor attached thereto is placed in a horizontal plane, the transmitting-receiving surface faces downward. A recess is formed in a peripheral portion of the reflection wall. The recess is receded toward a back surface of the reflection wall, namely, in a direction away from the transmitting-receiving surface.
