ABSTRACT:
A temperature sensor comprising: a flange having a bore and mounted on a fluid pipe having a fluid flow, to prevent said fluid from leaking out; an MI cable formed to have metallic cores insulated and retained on a metallic outer cylinder, and fixed in such a mode in said bore that a leading end side of said MI cable protrudes from a leading end side of said flange and extends in an axial direction; a metallic cap fixed on a leading end side outer circumference of said MI cable and having fluid communication ports for allowing said fluid to flow therein; and a temperature sensing element including: a ceramic substrate housed in said cap; a sensing portion formed over said ceramic substrate and having electric characteristics varied with a temperature of said fluid; and a wiring portion for connecting said sensing portion and said metallic cores of said MI cable electrically.
