Each of pixels in a pixel array includes a photoelectric converter and a readout circuit which outputs a signal in accordance with charges generated in the photoelectric converter. The readout circuit includes a group of transistors which are disposed so as to form a current path fed by a current source. The readout circuit of a pixel in a first line in the array and the readout circuit of a pixel in a second line in the array are disposed between the photoelectric converter of the pixel in the first line and the photoelectric converter of the pixel in the second line. Directions of currents respectively flowing through the group of transistors in the readout circuit of the pixel in the first line and the plurality of transistors in the readout circuit of the pixel in the second line are the same. |
