Abstract: PROBLEM TO BE SOLVED: To ensure a longer life by improving a corrosion resistance, and improve an electric connectivity between a pad portion and a lead pin of a sensor board. SOLUTION: A gas sensor includes the corrosion-resistant sensor board 3 disposed in a measurement space S1, provided with a circuit element 33 for detecting a sample gas, and having the gold or platinum pad portion 34 serving as a wiring connection of the circuit element 33; the nickel alloy lead pin 5 wherein one end 5a is disposed in the measurement space S1 and electrically connected to the pad portion 34, and the other end 5b is disposed outside the measurement space; and a gold or platinum connection 6 which electrically connects between the pad portion 34 and the one end 5a of the lead pin 5. A first layer 7 comprising chromium, tungsten or titanium is formed at the one end 5a of the lead pin 5, and a second layer 8 comprising gold or platinum is formed on the first layer 7.

Abstract: 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.
