Claim:
A photoelectric conversion apparatus comprising: a plurality of pixels, each pixel comprising: a photoelectric conversion element configured to convert incident light to electric carriers, an amplifier section, which includes an input unit which is a floating diffusion, configured to read signals based on the electric carriers generated in the photoelectric conversion element, a transfer section configured to transfer the electric carriers in the photoelectric conversion elements to the input unit and a voltage supply section, which includes a transistor having a gate and a drain, configured to set potentials of the input unit to at least first and second potentials; a plurality of output lines configured to read signals from the amplifier sections; and a plurality of voltage supply lines configured to supply voltages to the voltage supply sections, and which select the first potential or the second potential and supply a voltage corresponding to the selected potential to the drain of the transistor, wherein each amplifier section is connected to one of the output lines without a select transistor therebetween, wherein the photoelectric conversion elements, the amplifier sections, the transfer sections, and the voltage supply sections are arranged in a two-dimensional array, wherein each pixel is changeable to a selection state in which signals are output from the amplifier sections to the output lines by the first potential, and to a non-selection state in which signals are not output from the amplifier section to the output lines by the second potential, wherein out of the plurality of output lines and the plurality of voltage supply lines, only one output line and one voltage supply line are disposed between a first photoelectric conversion element and a second photoelectric conversion element adjacent to the first photoelectric conversion element, signals based on electric carriers generated in the first photoelectric conversion element being read through the one output line, voltages being supplied, through the one voltage supply line, to one of the voltage supply sections that sets a potential of one of the input units to which the electric carriers generated in the first photoelectric conversion element are transferred, wherein a wiring connected to the gate of the transistors is constituted by a wiring layer different from a wiring layer of the voltage supply lines and the output lines, wherein each of the floating diffusions is provided for a corresponding photoelectric conversion element individually, and a predetermined number of the floating diffusions are electrically connected to each other and electrically connected to a gate of a common amplifier transistor by a wiring line, and wherein the wiring line is in a different plane from the one voltage supply line and does not overlap the one voltage supply line.
