Title:
TEMPERATURE SENSOR AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/113821
Kind Code:
A1
Abstract:
A temperature sensor (1) is provided with: a temperature-sensitive element (10) for sensing a temperature; metal lead wires (20, 20a, 20b) formed from a metal material and having an extension part (21) extending along a reference direction (Db), the metal lead wires (20, 20a, 20b) being electrically connected to the temperature-sensitive element; a resin casing (40) formed from a resin material, the metal lead wires being inserted into the resin casing (40) by molding in a mold; and a middle cover (50) formed from a specific material having a coefficient of linear expansion in the reference direction greater than that of the metal lead wires and less than that of the resin casing, the middle cover (50) being interposed between the resin casing and the metal lead wires. The difference in coefficient of linear expansion between the metal lead wires and the middle cover in the reference direction is set in a specific range whereby stress that occurs in the metal lead wires in response to the difference in coefficient of linear expansion is limited so as to be less than the tensile strength of the metal lead wires.
