description Disclosed is an electrostatic discharge protection device which includes a substrate including a first well having a first conductivity type and a second well surrounding the first well, first to fifth diffusion regions formed on the first well, and sixth and seventh diffusion regions formed on the second well. The second diffusion region surrounds the first diffusion region, the fourth diffusion region surrounds the fifth diffusion region, and the fifth diffusion region surrounds the second diffusion region and the fourth diffusion region. The sixth diffusion region surrounds the fifth diffusion region, and the seventh diffusion region surrounds the sixth diffusion region. The sixth and seventh diffusion regions are connected to an anode electrode, and the first to fifth diffusion regions are connected a cathode electrode.
