Patent ID: 8398837

Claim:
A sensor comprising a plate-shaped sensor element extending in a front-rear direction and having a plurality of electrode terminals; a plurality of metallic terminal members connected to the electrode terminals of the sensor element; and a separator surrounding and insulating the plurality of metallic terminal members, wherein at least three electrode terminals are provided on at least one side surface of the sensor element at intervals in a lateral direction normal to the front-rear direction; individual ones of the plurality of metallic terminal members each has a plate spring portion formed at a front end thereof, and a crimp portion formed at a rear end thereof and connecting to the plate spring portion; the plate spring portion is pressed against the corresponding electrode terminal to thereby electrically connect the plate spring portion to the electrode terminal; a lead wire is crimp-connected to the crimp portion to thereby electrically connect the lead wire to the crimp portion; and the lead wire is passed through one of a plurality of through holes of an elastic seal member disposed on the rear-end side of the separator, and is extended to the outside, the through holes being formed in the elastic seal member generally along a circle, the sensor being characterized in that of the metallic terminal members connected to the at least three electrode terminals, side metallic terminal members located at opposite ends with respect to the lateral direction are crimp-connected to lead wires by means of crimping fingers of the crimp portions of the side metallic terminal members that are bent toward the side where the electrode terminals are present; and a remaining metallic terminal member is crimp-connected to a lead wire by means of crimping fingers of the crimp portion of the remaining metallic terminal member that are bent toward the side opposite the side where the electrode terminals are present.
