Abstract
A temperature sensor according to the present invention includes a sensor body for sensing a temperature; a sheath pin core wire electrically connected to the sensor body; a connector electrically connecting between the sheath pin core wire and the lead wire; and a protection tube for containing the connector and the sheath pin core wire, and for protecting the connector and the sheath pin core wire. A connection portion between the sheath pin core wire and the lead wire is hardened by a ceramic material so that a molded portion is provided. A displacement limiting means is provided for limiting displacement of the molded portion exceeding a predetermined value in the protection tube. The present invention can sufficiently reduce the tension acting on a sheath pin core wire. Further, the present invention can provide an exhaust temperature sensor having a sufficiently low tension acting on the sheath pin core wire which can be effectively used in an internal combustion engine.
