Abstract

A small-sized surface-mounted fuse and a method of manufacturing the same. A fusing element, separated from a winding member, is connected to lead wires by arc welding instead of soldering. Consequently, the present invention has the effect of improving fusing characteristics and productivity while reducing the defective rate and manufacturing costs. To this end, the manufacturing method according to the present invention comprises winding a fusing element predetermined winding turns on a winding member having a predetermined length, cutting both ends of the fusing element wound the predetermined winding turns on the winding member, separating the fusing element having the cut ends from the winding member, pressing the upper ends of lead wires 11 inserted through two through-holes formed at a base while being spaced a predetermined distance from each other such that the upper ends have predetermined areas, respectively, putting he ends of the fusing element on the pressed upper ends of the lead wires, connecting the ends of the fusing element to the upper ends of the lead wires by arc welding, and covering the base with a cover.
