A photoelectric transfer device includes at least one photoelectric transfer cell having the following elements: A photoelectric transfer element generates a photoelectric current based on a quantity of incident light. An amplifier element includes first FET and functions as a source follower in which a source voltage of the first FET is varied so as to follow up a gate voltage thereof. A read unit outputs, as an output signal, the source voltage of the source follower. The photoelectric transfer element is connected to a gate and source of the amplifier element so that a voltage between the gate and source of the amplifier element is applied across the photoelectric transfer element.
