Title: Temperature sensor and method of manufacturing the same

Abstract: A low cost high-performance temperature sensor that can be manufactured ofa thin-film temperature detecting element with high yield. The temperaturesensor has a metal cylinder (10); a ceramic substrate (2) placed in themetal cylinder and a temperature detecting element (3) and film electrodes(94) connected with the output of the temperature detecting element (3);an inorganic filer (95) for absorbing stress to hold the ceramic substrate(2) inside the metal cylinder (1); and a cap (6), provided on one end ofthe metal cylinder (1), for protecting the temperature detecting element(30) on the ceramic substrate (2). One end of the ceramic substrate isfixed to a first end of a terminal (27) which is U-shaped, and theterminal includes an expansion and contraction absorbing portion (20)between a first and second end.
