Title:
FUSE ELEMENT AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2015/059955
Kind Code:
A1
Abstract:
Provided is a fuse element which can be surface-mounted by a reflow process and is capable of interrupting an electric current more reliably.
A fuse element (1) which is provided with: a substrate (2); a conductive wiring line (13) which is arranged on the substrate (2); and low-melting-point metal layers (20, 21) which are arranged so as to directly or indirectly cover a part of the conductive wiring line (13) and have a lower melting point than the conductive wiring line (13), and which become a melt so as to form a fused part by melting the conductive wiring line (13). The low-melting-point metal layers (20, 21) are formed of pure Bi or a Bi-based alloy that contains 80% by weight or more of Bi.
