Abstract
In a photoelectric conversion device, groups of unit pixels are arranged in a well, where each of the unit pixels includes photoelectric conversion elements, an amplifier transistor, and transfer transistors. The photoelectric conversion device includes a line used to supply a voltage to the well, a well-contact part used to connect the well-voltage-supply line to the well, and transfer-control lines used to control the transfer transistors. The transfer-control lines are symmetrically arranged with respect to the well-voltage-supply line in respective regions of the unit-pixel groups.
