Abstract

A sensing sensor includes an oscillator circuit, a base, a connection portion, and a temperature changing unit. The oscillator circuit oscillates the piezoelectric resonator. The base includes a base main body in which a depressed portion is provided and a lid portion at one side, supports the piezoelectric resonator at another side, and is for taking the oscillation frequency to an outside of the sensing sensor. The depressed portion houses the oscillator circuit. The lid portion covers the depressed portion. The connection portion is disposed at the one side of the base and connected to a cooling mechanism for cooling the base from the one side. The temperature changing unit is interposed between the piezoelectric resonator and the base, so as to cool and heat the piezoelectric resonator and transfer a heat radiated for cooling the piezoelectric resonator from the other side of the base to the one side.
