The present invention provides a fuse that can be easily manufactured and has an improved yield. A fuse includes an input terminal portion, a bus bar portion through which a current input from the input terminal portion flows, and a terminal portion connected to the bus bar portion through a fusible portion, where a fusible portion unit including the fusible portion and the terminal portion is provided in plurals, each of the fusible portion units is a separate body from the bus bar portion and is individually attached to the bus bar portion.
