Abstract: A temperature sensor includes: a temperature sensing element including a temperature sensing portion, electrical characteristics of which vary depending on temperature, and an electrode wire for outputting an electric signal from the temperature sensing portion to the outside; and a sheath core wire (signal wire) electrically connected to the electrode wire. The electrode wire is made of a platinum-rhodium alloy. The platinum-rhodium alloy is composed of 0.1 to 1.5 mol % of Sr, 22 to 40 mol % of Rh, and a remainder composed of Pt and unavoidable impurities. The platinum-rhodium alloy has a second-phase mainly composed of Sr and Pt whose precipitated grains are dispersed in a matrix phase. An area ratio of the second phase at a cross section is not greater than 25%.

Abstract: Provided is a spark plug capable of ensuring fouling resistance with a simple configuration. An insulator includes a step portion formed on an outer circumferential surface thereof. A center electrode is arranged in an axial hole of the insulator. A cylindrical metal shell having a shelf portion formed on an inner circumferential surface thereof is arranged radially outside the insulator. The insulator further includes a front end portion located frontward of the step portion. An outer circumferential surface of the front end portion has an arithmetic average roughness of 0.5 μm or smaller in a circumferential direction. A recess is formed with a depth of 3 to 20 μm in at least part of an end surface and the outer circumferential surface of the front end portion so as to extend from the front toward the rear.
