A gas sensor in which respective terminal leads are fitted and connected to respective electrodes on inner and outer circumferential surface of a hollow, cup-shaped detection element When a leading end connecting portion of a terminal lead ( 71, 91 ) is disposed on the front end side of a separator ( 111 ) and an intermediate portion ( 74, 94 ) extending from the rear end of the leading end connecting portion is inserted into a hole ( 113 ), a spring tab ( 77, 97 ) provided on the intermediate portion ( 74, 94 ) is pressed against a second wall surface ( 117 ) of the hole ( 113 ), whereby an engagement portion ( 76, 96 ) is pressed against a first wall surface opposite the second wall surface ( 117 ). The first projection ( 118 ) is formed on the first wall surface of the hole ( 113 ) so that it can come into contact with and support a first face ( 76 b , 96 b) of the engagement portion ( 76, 96 ) on opposing lateral sides of the spring tab ( 77, 97 ).
