A sensor structure is disclosed which reduces the resistance of insertion in the course of insertion of a metallic terminal member into the hollow portion of an oxygen detection element so as to enable smooth assembly and such that portions of the metallic terminal member become less susceptible to plastic deformation. <??>An attachment portion (23c) of a metallic terminal member (23) is in contact with the inner wall surface of a hollow portion (2a) of an oxygen detection element (2), directly or indirectly via another member, at opposite sides thereof located along the direction of contact. Also, a gap (5) is formed between an attachment portion (23c) and the inner wall surface at opposite sides of the attachment portion (23c) located along the direction of gap (5) formation. Thus, in the course of insertion of the metallic terminal member (23) into the hollow portion (2a) of the oxygen detection element (2), the resistance of insertion decreases, whereby assembly can be performed smoothly, and portions of the metallic terminal member (23) become less susceptible to plastic deformation, such as crushing bending, or buckling. <IMAGE> |
