Temperature sensor

A temperature sensor comprising:

• a temperature sensitive element configured to detect a temperature;
• a sheath pin comprising core wires which are electrically connected to the temperature sensitive element;
• lead wires corresponding to the core wires of the sheath pin, through which a detection signal of the temperature sensitive element is output to an outside device;
• connectors through which the core wires of the sheath pin and the lead wires are electrically connected together;
• and
• a protection tube configured to accommodate the core wires of the sheath pin, the lead wires and the connectors, and equipped with a supporting member made of an elastic member having inserting and supporting holes through which the connectors are inserted and supported, and the protection tube, the supporting member and the lead wires being caulked together, and a stress applied to the core wires of the sheath pin connected to the lead wires being smaller than a critical strength of elastic deformation of the core wires of the sheath pin,
• wherein each of the connectors comprises a circular arc part and claw parts, the circular arc part is made along a profile of an outer circumference of a front end part of each lead wire, and the claw parts are formed at both the end parts of the circular arc part, and each of the claw parts pushes an inner wall surface of the corresponding inserting and supporting hole;
• and
• each of the connectors is supported by the inner wall surface of the inserting and supporting holes to deform the inner wall surface of the corresponding inserting and supporting holes by a front end of each of the claw parts of each of the connectors.
