Disclosed is an imaging device including a photodiode and floating diffusion region formed to be spaced from each other on a surface layer of a pixel region of a silicon (semiconductor) substrate, and a transfer gate having one of a concave and convex portions toward the floating diffusion region, the transfer gate being formed above the silicon substrate between the photodiode and the floating diffusion region by interposing a gate insulating film therebetween.
