Patent ID: 8156790

Claim:
A sensor comprising: a detection element in the form of an axially extending plate, having a front end side to face an object to be measured and formed with an electrode terminal section at a rear end side; a separator made of an insulating material and having an element insertion hole accommodating the rear end side of the detection element; and a metallic terminal member interposed between the detection element and an inner surface of the element insertion hole of the separator; characterized in that: the metallic terminal member is formed from a metallic sheet material and having an axially extending frame main body section, an element abutment section extending while being bent to change the direction of extension, from a front end of the frame main body section axially toward a rear end side of the frame main body section and contacting the electrode terminal section of the detection element thereby being electrically connected thereto to form a current path, and a frame locking section having a first locking surface facing axially toward a rear end side of the frame main body section and a second locking surface facing in the direction of an intervening space between the frame main body section and the element abutment section and toward the element abutment section; and the separator has a locking groove for disposition of the frame locking section and engages at an inner wall surface of the locking groove with the first locking surface and the second locking surface.
