Abstract

A gas sensor includes: a sensor element including a sensing part on one end portion thereof; a casing; and a connector disposed in the casing to electrically connect the sensor element to an outside, wherein the casing includes: an outer tube including a main portion in which a reference gas is included and a sealing portion with a diameter smaller than the main portion so that another end portion of the sensor element protrudes to the main portion; a rubber seal member fitted into the sealing portion; and a spacer intervening between the seal member and the connector, and the spacer is secured by being sandwiched between the connector and the seal member due to friction force acting on a contact surface with the seal member which occurs by that load acts on the spacer from the seal member in accordance with reduction in the diameter by swaging.
