PROBLEM TO BE SOLVED: To provide a fuse circuit of which circuit area is reduced, as compared with a conventional one. SOLUTION: A semiconductor device includes the fuse circuit which includes a fuse element and an MOS transistor element whose drain region or source region is electrically connected to one end of the fuse element, in order to supply a current required for melting the fuse element, and which is electrically programmable by selective melting of the fuse element; and the fuse element is positioned on an insulating film directly above the formation region of the MOS transistor element.
