Abstract
A photoelectric-conversion apparatus includes a photoelectric-conversion area where a plurality of photoelectric-conversion elements configured to convert incident light into electrical charges, a plurality of floating-diffusion areas, a plurality of transfer-MOS transistors configured to transfer electrical charges of the photoelectric-conversion element to the floating-diffusion area, and a plurality of amplification-MOS transistors configured to read and transmit a signal generated based on the transferred electrical charges to an output line are provided. An antireflection film is provided on a light-receiving surface of the photoelectric-conversion element. The gate of the amplification-MOS transistor is electrically connected to one floating-diffusion area by providing one conductor in a single contact hole, and the anti-reflection film covers the photoelectric-conversion area except a base part of the contact hole.
