Abstract
A temperature sensor element for measuring the temperature of exhaust gas from car engines comprises a metallic support having a shape of a flat board, a first electric-insulating film existing on the support, a first temperature sensitive film existing on the first electric-insulating film and having a pair of electrodes, and a second electric-insulating film existing on the temperature sensitive film. The element is superior in thermal shock resistance. The element needs no heat-resistant cap. The element is superior in heat-response since the element has a small heat capacity.
