Photoelectric conversion apparatus, photoelectric conversion system, and moving body

A photoelectric conversion apparatus including a semiconductor layer and a wiring structure, wherein

• the semiconductor layer includes a pixel array region including a plurality of pixels, a scribe region including an outer edge of the semiconductor layer, a peripheral region arranged between the pixel array region and the scribe region, and an isolation portion configured to electrically isolate the peripheral region and the scribe region,
• each of the plurality of pixels includes an avalanche photodiode,
• the peripheral region includes a first region of a first conductivity type containing, as a majority carrier, a charge with a first polarity, a second region of the first conductivity type, and a third region of a second conductivity type containing, as a majority carrier, a charge with a second polarity different from the first polarity,
• the scribe region includes a fourth region of the first conductivity type,
• the wiring structure includes an electrically conductive path configured to electrically connect the second region and the fourth region, and
• the wiring structure includes a first voltage supply line configured to supply a first voltage to the first region to extract the charge with the first polarity from the peripheral region through the first region, and a second voltage supply line configured to supply a second voltage to the third region to extract the charge with the second polarity from the peripheral region through the third region.
