    • The object of the present invention is to provide a low power consumption, compact radio wave sensor capable of accurately detecting the presence and mobile status of a detected object present within a detection area, and having a superior S/N ratio. The radio wave sensor comprising: an oscillator circuit 1 for producing a high-frequency signal; a ground electrode 3 formed on one surface of a substrate 2 formed of a dielectric body or on approximately the entire surface of the interior thereof, acting as ground to a high-frequency signal; an antenna electrode 6 formed on the other surface of the substrate, for radiating a high-frequency signal as a radio beam and receiving a radio beam which collides with a detected object and is reflected back from the object; and a wave detecting element 7 for detecting a high-frequency signal received by the antenna electrode 6; wherein one of the terminals of the wave detecting element 7 is connected to the antenna electrode 6 via a frequency adjustment line 12 for adjusting the frequency of the antenna electrode 6, and the other terminal is connected to the ground electrode 3; and the frequency adjustment line 12 is connected to the antenna electrode 6 at a position different from that of an electrical feeding point (in Fig., a position of a conducting hole 13a) provided on the antenna electrode 6 to supply electricity to the antenna electrode 6 with the high-frequency signal produced by the oscillator circuit 1.
