PURPOSE: A semiconductor device equipped with a fuse part is provided to prevent a structure which is adjacent to a fuse to be damaged in a repair process by including a dummy fuse and a dummy plug. CONSTITUTION: A plurality of fuses(23) is formed on an inter-layer insulating film. A dummy fuse(24) is separated with the fuse and is located between the fuses. A dummy plug(25) is connected to the dummy fuse by passing through the inter-layer insulating film. The dummy plug is connected to a ground terminal. The fuse and dummy fuse are composed of a metal wiring which is located on the same level. A protective film covers the fuse and the dummy fuse. The dummy fuse and the dummy plug are a line pattern. A fuse box is formed in the protective film. The length of the dummy fuse is longer than the length of the fuse box.
