Abstract: Diffusion regions having the same conductivity type are arranged on a side of a second wiring and a side of a third wiring, respectively under a first wiring connected to a signal terminal. Diffusion regions are separated in a whole part or one part of a range in a Y direction. That is, under first wiring, diffusion regions are only formed in parts opposed to diffusion regions formed under the second wiring and third wiring connected to a power supply terminal or a ground terminal, and a diffusion region is not formed in a central part in an X direction. Therefore, terminal capacity of the signal terminal can be reduced without causing ESD resistance to be reduced, in an ESD protection circuit with the signal terminal.
