Abstract: A temperature sensor includes a temperature detector, an element electrode wire, a lead wire, and an intermediate member. Each of the lead wire and the intermediate member is made of a Ni-based alloy or an Fe-based alloy. The element electrode wire and the intermediate member are welded together in such a manner that opposing surfaces, facing each other abut against each other to constitute an element-side weld. The intermediate member and the lead wire are welded together such that they overlap each other in a longitudinal direction Z to constitute a lead-side weld. The lead wire is extended closer to the temperature detector than the element-side weld is located. A gap between the element electrode wire and the lead wire at least in the longitudinal direction Z is filled with a filler. The element electrode wire, the element-side weld, and the lead wire are fixed to one another by the filler.

Abstract: A temperature sensor includes a temperature detector having a thermosensitive element, element electrode wires, leads, and intermediate members. The temperature sensor is formed such that ends of the element electrode wires are embedded in the temperature detector, the leads are electrically connected to the respective element electrode wires, and the intermediate members electrically connect the element electrode wires to the respective leads. Each element electrode wire and the corresponding intermediate member are arranged being aligned in the extending direction, and bonded to each other, with opposing surfaces facing each other being abutted each other. The intermediate member and the corresponding lead are juxtaposed in a direction perpendicular to the extending direction, and bonded being overlapped with each other.
