PROBLEM TO BE SOLVED: To provide a semiconductor device or the like that secures a sufficient compensation capacitance by effectively utilizing a region in a circuit cell so as to surely suppress variations in power supply voltage. SOLUTION: The semiconductor device comprises a circuit cell 2 including a plurality of elements arranged side by side in a first direction, and a basic end cell 1 (1a). The basic end cell has compensation capacitors C1, C2 adjacently arranged in the first direction of the circuit cell 2 so as to be connectable to a power supply of the circuit cell 2. Diffusion layers 10, 11 constituting the compensation capacitors C1, C2 are extendingly formed along the first direction in a predetermined region (an inter-element connection region R1) of the circuit cell 2. Gate wirings 16, 17 are also extendingly formed above the diffusion layers 10, 11. By such a configuration, it is possible to surely suppress variations in power supply voltage by increasing each capacitance value of the compensation capacitors C1, C2 while effectively utilizing the inter-element connection region R1 of the circuit cell 2.
