摘要： The present invention relates to a radiation thermometer for measuring temperature of the eardrum at noncontact. The thermometer comprises a signal processor 4 for calculating a temperature from an output of a light receptor 17, which receives only the infrared rays radiated directly from the eardrum and/or vicinity of it, and notification means 18 for notifying the temperature resulted from the calculation. Since the structure does not receive an influence of any radiant heats from other than those of the eardrum and/or vicinity of it, temperature change of a probe 1 does not become a factor of measuring errors, so as to offer an accurate measurement of temperatures. An infrared-ray-receiving element is positioned within a triangle configured by an intersection between a light path and an optical axis, and two image points of hypothetical end points formed by an optical condenser, when viewed in a cross sectional plane including the optical axis of the optical condenser, where (a) the light path is a path that extends from the hypothetical end point to the image point of the hypothetical end point formed by the optical condenser by passing through a rim of the optical condenser on the same side as the hypothetical end point with respect to the optical axis, and (b) the hypothetical end point is a point at which a straight line drawn from the rim of the optical condenser toward the probe in a manner to be tangent to an inner surface of the probe on the same side as the rim of the optical condenser with respect to the optical axis crosses a plane at a tip of the probe.
