Abstract

A temperature sensor includes a ceramic layered product having a multilayer structure formed of a plurality of ceramic sheets containing an unreducible ceramic material, a plurality of resistive patterns, containing copper or nickel, formed on major surfaces of the plurality of ceramic sheets respectively, a conductive path passing through the ceramic sheets for series-connecting the plurality of resistive patterns with each other, and respective terminals connected to both ends of the series-connected plurality of resistive patterns.
