Document Type and Number:
WIPO Patent Application WO/2022/181652
Kind Code:
A1
Abstract:
The present invention provides a protection element which is capable of safely and quickly blocking a current path without causing breakage of an insulating layer or a heating element. This protection element is provided with an insulating substrate 2, a fusible conductor 3 that is arranged on and supported by the insulating substrate 2, a plurality of current-carrying parts 4 that are connected to the fusible conductor 3, a heating element 5 that is provided onto the insulating substrate 2 and generates heat when a current is passed therethrough, a heating element electrode 6 that is connected to the heating element 5 and serves as a feed terminal for the heating element 5, and a glass layer 7 that covers the heating element 5; and the glass layer 7 has a melting point that is lower than the melting point of the heating element 5.
