Abstract:
A protective element, comprising:an insulating layer; a first PTC element formed of PTC material; a low-melting-point metal member; and a heat-generating member, wherein the PTC material forming the first PTC element serves as a substrate for the low-melting-point metal member or the heat-generating member, wherein the low-melting-point metal member is provided between a first terminal of the protective element and a second terminal of the protective element, and the heat-generating member and the first PTC element are connected in series between the first terminal of the protective element and a third terminal of the protective element, and wherein at least one selection from the group consisting of the heat-generating member, the first terminal, the second terminal, the third terminal, and the insulating layer is formed by coating directly on the substrate.
