Abstract
An oxygen sensor element is inserted and fixed in a housing. A base body is provided at an end of the housing. The base body is made of a resin. The base body has a flange at an end. The housing has a caulking portion which is deformable when received a pressing force acting in a direction parallel to an axis of the oxygen sensor. By deforming the caulking portion, the flange is tightly connected with the caulking portion.
