MANUFACTURING METHOD OF FUSE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an inexpensive fuse.SOLUTION: A manufacturing method of a fuse includes: a heat spot manufacturing step of manufacturing a heat spot part 3 having a cross sectional area smaller than that at other places by rolling a part of a wire 2 by using the wire 2 formed by bundling a plurality of conductive material element wires 2a; a heat dissipation part manufacturing step of manufacturing a heat dissipation part 4 having a surface area wider than that at other places of the wire 2; and an inter-element wire deposition step of depositing a place where the plurality of element wires 2a of the wire 2 are bundled.
