置。 An oscillation circuit section using a dielectric resonator, a detection section that detects changes in capacitance with the detected object, and a resonant circuit whose tuning point changes due to minute changes in capacitance detected by this detection section. The dielectric resonator is disposed on one side of a double-sided printed circuit board, and the dielectric resonator is disposed on the opposite surface of the printed circuit board. A circuit excluding the resonator is formed, and a shielding member is provided integrally with the printed circuit board in a region near where the dielectric resonator is arranged to keep the stray distributed capacitance between the dielectric resonator and the dielectric resonator constant. Electrostatic sensor device.
