Abstract
Provided are: a temperature sensor capable of ensuring reliability and improving thermal responsiveness; and a device equipped with such a temperature sensor. The present invention is provided with: a surface-mounted heat sensitive element (10) having at least a pair of electrode parts (12a), (12b); lead parts (22a), (22b) that are electrically connected to the pair of electrode parts (12a), (12b) by welding; a holder (21) that holds and fixes the lead parts (22a), (22b); and an insulation coating part (23) that insulates at least a portion of the lead parts (22a), (22b) and the heat sensitive element (10). The lead parts (22a), (22b) are tabular metal plates and are formed of a metallic material having a melting point of not more than 1300° C.
Claims19
A temperature sensor comprising:
- a surface-mounted heat sensitive element which comprises at least a pair of electrode layers;
- at least a pair of electrode parts connected to exposed parts of the pair of electrode layers;
- lead parts which are electrically bonded to the pair of electrode parts by welding;
- a holder which fixes and holds the lead parts;
- and
- an insulation coating part which insulates at least portions of the heat sensitive element and the lead parts,
- wherein the pair of electrode parts comprise an active layer containing a high-melting point metal as a main component, a barrier layer containing another high-melting point metal as a main component formed on the active layer, and a bonding layer containing a low-melting point metal as a main component formed on the barrier layer.
