Abstract
A temperature sensor includes a ceramic layered product having a multilayer structure formed of a plurality of ceramic sheets, 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. The ceramic sheets being formed of an unreducible ceramic material prepared from a TiO.sub.2.BaO.CaO.ZrO.sub.2 compound.
