The present invention relates to busbar for a multi-fuse. The busbar (20) of the present invention has an input terminal unit (22) connected to a power supply side and a connection portion (24) extending long from the input terminal unit (22) in one direction. Multiple output terminal unit (26) are arranged side by side in a direction vertical to a length direction of the connection portion (24). A resistance forming unit (28) connects the output terminal units (26) and the connection portion (24) and includes a melting portion (30). A low melting point metal (34) is prepared at the melting portion (30) and a fixing portion (32) is formed at the melting portion (30) to temporarily fix the low melting point metal (34) before melting. The fixing portion (32) is formed as a concavity at the melting portion (34), which penetrates the melting portion (30) or is formed into a groove shape. According to the present invention, since the size of the fixing portion (32) for temporarily fixing the low melting point metal (34) is reduced, each distance between the multiple output terminal units (26) can be minimized. Thus, the overall size of the busbar (20) is reduced and the multi-fuse can be smaller. |
