Abstract
A temperature sensor includes a pair of element electrode wires extending rearward from a temperature-sensing portion. A pair of second electrode wires are welded to the element s electrode wires, and made of a kind of metal having a different thermal expansion coefficient than the element electrode wires. Each second electrode wire includes an overlap section overlapping with an overlap section of the corresponding element electrode wire over an overlap region in a longitudinal direction in which the overlap sections of the each second electrode wire and element electrode wire extend longitudinally. The overlap section of each second electrode wire is welded to the overlap section of the corresponding element electrode wire at weld zones arranged in the longitudinal direction, which include: one at a front-side end of the overlap region; and another at a rear-side end of the overlap region.
