WIPO Patent Application WO/2014/034261
Kind Code:
A1
Abstract:
Provided is a fuse which can reliably cut off overcurrent. A fuse (1) is provided with an insulating substrate (10), wiring (11), a low melting point metal part (20), and a heating element (30). The wiring (11) is arranged on one main surface (10a) of the insulating substrate (10). The low melting point metal part (20) is disposed on the wiring (11). The low melting point metal part (20) has a lower melting point than the wiring (11). The low melting point metal part (20) dissolves the wiring (11) when the low melting point metal part (20) turns into melt. The heating element (30) heats the low melting point metal part (20). In planar view, the heating element (30) is disposed further towards one side of a region on which the low melting point metal part (20) is arranged than the edge of the other side in the direction in which the wiring (11) extends.
