Abstract
A temperature sensor () including: a temperature sensing element () including a temperature sensing portion () having an electrical characteristic which varies depending on temperature, and an electrode wire () for outputting an electrical signal from the temperature sensing portion (); and a sheath core wire (signal wire) () electrically connected to the electrode wire (). The electrode wire () is formed from a platinum-palladium-rhodium alloy containing Pt, Pd and Rh. The alloy contains a total of 0.1 to 1.2 mol % of at least one alkaline-earth metal selected from the group consisting of Ca, Sr and Ba; 0.1 to 43.0 mol % of Pd; and 1.0 to 43.0 mol % of Rh, and the balance is Pt and incidental impurities. In the platinum-palladium-rhodium alloy, second-phase precipitated grains mainly containing Pt, Pd and the alkaline-earth metal are dispersed in a matrix phase.
