Abstract
A sensor having a terminal connection structure in which an elongated sensor element (21) is inserted, from its rear end through relative movement, into a metallic-terminal-member retainer. Metallic terminal members (51) are elastically deformed and pressed against corresponding electrode terminals (25) formed on side surfaces (26) of the sensor element. A chamfer (28) is formed on a rear edge of sensor element (21). Rear ends (25b) of the electrode terminals (25) are biased from the chamfer (28) toward a front end of the element (21). A flat surface (26b) is present between the rear ends (25b) of the electrode terminals (25) and a front end (28a) of the chamfer (28). During insertion of the element (21), a large force generated when the metallic terminal members (51) pass over the chamfer (28) is not directly applied to the rear ends (25b) of the electrode terminals (25), thereby preventing damage to the electrode terminals (25).
