PROBLEM TO BE SOLVED: To attain sure fuse welding by stably separating a fuse welding position from a conductive layer. SOLUTION: A fuse 3 provided with a fuse body 3A and two pads 3Ba, 3Bb connected by the fuse body 3A and two conductive layers 5A, 5B respectively connected to respective pads 3Ba, 3Bb are formed in a laminated structure on a semiconductor substrate. When the fuse 3 is welded by impressing electric stress between the two conductive layers 5A, 5B, the length of the fuse body 3A is regulated so that the welding part of the fuse 3 is located on a position in the fuse body 3A which is separated from an area superposed to the conductive layer 5A or 5B.
