Claim:
1. A solid state imaging device comprising: a semiconductor layer of a first conductivity type; a gate insulation film that is located on the semiconductor layer; a gate electrode that is located on the gate insulation film; a first impurity region of a second conductivity type that is located in the semiconductor layer and is located, as viewed in plan view, at least in a region outside the gate electrode on a first end portion side, the first impurity region constituting a photodiode; a second impurity region of the second conductivity type that is located in the semiconductor layer and is located, as viewed in plan view, in a region extending across a second end portion that is opposite to the first end portion of the gate electrode, the second impurity region storing charges transferred from the photodiode; and a third impurity region of the first conductivity type that is located in the semiconductor layer, is located on top of the second impurity region at a position outside the gate electrode on the second end portion side as viewed in plan view, and is in contact with the second impurity region.
