Claim:
1. An imaging device comprising: a substrate; a photoelectric conversion section disposed in the substrate; an element isolation region disposed adjacent to the photoelectric conversion section; a floating diffusion electrically connected to the photoelectric conversion section; an amplification transistor having a gate electrode and an active region; and a contact section disposed on the gate electrode of the amplification transistor, wherein the contact section overlaps the active region of the amplification transistor, wherein, the floating diffusion is electrically connected to the gate electrode of the amplification transistor via the contact section, a width of the gate electrode of the amplification transistor is larger than a width of the active region of the amplification transistor, the photoelectric conversion section includes a first type impurity, and the element isolation region includes a second type impurity having a conductivity opposite to the first type impurity.
