ABSTRACT:
An oxygen concentration detector easily assembled without producing conducting malfunctions at an external electrode includes a cylindrical housing and a detecting element being inserted into and disposed inside the housing. Powdery seal materials made of ceramic power are filled under pressure between a top portion of the detecting element and the housing. The detecting element has the external electrode at an external surface thereof and a lead portion extending upwardly from the external electrode. A ring-shaped conducting member is installed between the lead portion of the detecting element and the housing as a ground to conduct electricity therebetween and has a resilient contacting piece in contact with the lead portion at an inner peripheral portion of the ring-shaped conducting member.
