Abstract
A photoelectric conversion apparatus includes a semiconductor layer having an avalanche photodiode, and a wiring structure electrically connected to the semiconductor layer. In a plan view, the photoelectric conversion apparatus comprises a pixel region including the avalanche photodiode, and a peripheral region located between the pixel region and an outer edge of the photoelectric conversion apparatus. A third wiring layer is located between a first wiring layer and a second wiring layer. The first wiring layer includes, in the peripheral region, a first conductive part for transmitting an anode potential of the avalanche photodiode. The second wiring layer includes, in the peripheral region, a second conductive part for transmitting a second potential different from the anode potential. The first conductive part and the second conductive part overlap in the plan view.
