Document Type and Number:
WIPO Patent Application WO/2024/070418
Kind Code:
A1
Abstract:
Provided is a protective element capable of quickly and reliably melting and cutting even when the size of the cross-sectional area of a fuse element increases. This protective element 1 has: an insulating substrate 2; a heating body 4 provided on a surface 2a side of the insulating substrate 2; an insulating layer 5 which covers the heating body 4; an intermediate electrode 6 provided on the insulating layer 5; a fuse element 3 connected to the intermediate electrode 6; and a flux 7 provided on the fuse element 3, wherein the intermediate electrode 6 has a length which is the same as or greater than that of the heating body 4 in a direction perpendicular to the energization direction of the fuse element 3 and has a front-end section 4 extending further than the heating boy 4, and the flux 7 is applied, in a direction perpendicular to the energization direction of the fuse element 3, to pass the fuse element 3 and at least up to the same position as the heating body 4.
