摘要： PROBLEM TO BE SOLVED: To realize miniaturization, inhibit the effects of ambient temperature, as much as possible, reduce manufacture errors, such as, reference gas enclosure and the like, and improve a measurement sensitivity by enlarging a detection signal. SOLUTION: The thermal sensitivity sensor 100, having measurement resistors R1 and R2 to be brought into contact with a sample gas disposed on one opposite side and using a Wheatstone Bridge circuit WB, including reference resistors to be brought into contact with a reference gas disposed on the other opposite side, detects a thermal conductivity of the sample gas by comparing potential differences at connection points between the reference resistors R3 and R4 and between the measurement resistors R1 and R2. The measurement resistors R1 and R2, disposed on the one opposite side, are accommodated in one measurement space S1, and the reference resistors R3 and R4, disposed on the other opposite side, are accommodated in one reference space S2.
