A semiconductor integrated circuit device includes a power supply line connected to a power supply terminal, a ground line connected to a ground terminal and a plurality of capacitors connected in parallel between the power supply line and the ground line. The plurality of capacitors include a first capacitor arranged at a first distance from one of the terminals and a second capacitor arranged at a second distance which is larger than the first distance from the one of the terminals, and the first capacitor has a larger area than the second capacitor.
