Title: High-current fuse for vehicles

Abstract: A high-current fuse for vehicles is provided. This high-current fuse includes a conductive plate having a fuse and terminal connecting portions on both ends, and a resin case into which the conductive plate is insert-molded. A heat radiating portion for releasing heat generated from the fuse and the conductive plate when energized is provided on the outer surface of the resin case. The heat radiating portion is made up of a plurality of thin plates arranged on the resin case at regular intervals. The thin plates are situated in parallel with the energizing direction so as to strengthen the resin case. To keep the fuse away from both ends of the conductive plate, a pair of assisting plates facing to each other are formed in the middle of the conductive plate, and the fuse is disposed between the assisting plates. The fuse between the assisting plates is in the direction perpendicular to the energizing direction of the conductive plate.
