Document Type and Number:
WIPO Patent Application WO/2018/003497
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a temperature sensor able not only to prevent failures where a temperature-sensitive sintered body ends up coming out of a protective case together with a packing resin, but also to curb changes in properties of the temperature-sensitive sintered body and ensure reliability; and a device provided with this temperature sensor. A temperature sensor (1) is provided with: a protective case (2) that has a linear expansion coefficient of 7.5 to 19.5 × 10-6/°C; a temperature-sensitive sintered body (3) that is arranged inside the protective case (2); a lead wire (4) that is connected to the temperature-sensitive sintered body (3) and has a cross-sectional area of 0.097 mm2 or less; and a packing resin (6) that has a linear expansion coefficient of 7.5 to 19.5 × 10-6/°C and that is packed around the temperature-sensitive sintered body (3) inside the protective case (2).
