PROBLEM TO BE SOLVED: To obtain a gas sensor in which the number of components is reduced and in which an assembling man-hour to a circuit board or the like can be reduced. SOLUTION: This gas sensor 20 is provided with a housing 22b into which a gas to be measured can be introduced. In addition, the gas sensor is provided with a sensor part 28 which can detect oxygen gas or the like contained in the gas. In addition, the gas sensor is provided with a sensor stem 24 by which the sensor part 28 is supported inside the housing 22 and which is assembled integrally to the housing 22 by a bonding part 25. Thereby, a shutoff property between the inside and the outside of the housing 22 can be ensured, and it is not required to assemble the housing 22 and the sensor stem 24 separately to a circuit board or the like to be assembled. Consequently, a packing material such as an O-ring or the like is not required, the number of components is reduced, and an effect to reduce an assembling man-hour to the circuit board or the like is obtained. |
