PROBLEM TO BE SOLVED: To improve a power source noise reduction effect by a decoupling capacitor without increasing a chip area. SOLUTION: A semiconductor integrated circuit apparatus has a plurality of unit cells 1 provided on a semiconductor substrate, and a wiring layer supplying a power source to the plurality of unit cells. The wiring layer has ground potential wirings 3 and 4 applying a ground potential to each of the plurality of unit cells, power source potential wirings 2 and 5 applying a power source potential to each of the plurality of unit cells, and an insulating film provided between the ground potential wirings 3 and 4 and the power source potential wirings 2 and 5.
