By stably separating a melting location of a fuse ( 3 ) from conductive layers ( 5 A, 5 B), reliable melting of the fuse ( 3 ) is enabled. A fuse ( 3 ) including a fuse body ( 3 A) and two pads ( 3 Ba, 3 Bb) connected by this and two conductive layers ( 5 A, 5 B) individually connected to the two pads ( 3 Ba, 3 Bb) are formed in a multilayer structure on a semiconductor substrate ( 1 ). A length of the fuse body ( 3 A) is defined so that the melting location of the fuse ( 3 ) becomes positioned in the fuse body ( 3 A) away from the region overlapped on the conductive layer ( 5 A or 5 B) when an electrical stress is applied between two conductive layers ( 5 A, 5 B) and the fuse ( 3 ) is melted.
