Abstract
In a contact member for a gas sensor configured to fix a sensor element by sandwiching the sensor element in an insertion port defined by a pair of housing members to thereby obtain electrical connection with the sensor element, a restraint member provided at an outer circumference of the pair of housing members and having a restraint function for restraining a displacement of the pair of housing members within a predetermined range is used. The restraint member includes: two pressing surface portions to which a compression force that occurs when the annular member shrinkingly deforms is applied; a first side portion coupled perpendicularly to the two pressing surface portions; and a second side portion having an upper side portion coupled perpendicularly to one of the pressing surface portions and a lower side portion coupled perpendicularly to the other of the pressing surface portions.
