Claim:
1. A photoelectric conversion device comprising: a photoelectric conversion unit for outputting a electric signal base on a signal charge generated in a photoelectric conversion element, the photoelectric conversion unit including a first transistor; and a signal processing unit for processing the electric signal, the signal processing unit including a second transistor and a third transistor, wherein a gate insulation film of the second transistor is thinner than a gate insulation film of the first transistor, wherein the first transistor and the second transistor are first conductive type transistors, and the third transistor is a second conductive type transistor, wherein the signal processing unit has an electrode integrally including a first conductive type portion as a gate electrode of the second transistor and a second conductive type portion as a gate electrode of the third transistor, and an impurity concentration in the first conductive type portion is higher than an impurity concentration in a gate electrode of the first transistor.
