ABSTRACT:
A multielectrode type fuse element manufactured by forming a shallow shaving portion 1 of a definite width in the long fuse material 9 in a longitudinal direction so as to form a thin area 2, punching from portions of the thin area 2 dependently on electrical conduction capacities of fuses so as to form a plurality of blowout portions 3, 3, forming a hook-like extending portion 6 on one side across the thin area 2 at an upper end of an input terminal 4 disposed in a direction perpendicular to the longitudinal direction of the long fuse material 9, forming a plurality of output terminals 5, 5 by punching from the long fuse material on a side of the hook-like extending portion 6 of the input terminal 4 in parallel with the input terminal 4 at an equal pitch, and forming the blowout portions 3, 3 to connect one side of an upper portion of a vertical section of the input terminal 4 and a lower tip of the hook-like extending portion 6 with top end of the plurality of output terminals 5, 5.
