Abstract
A photoelectric conversion apparatus according to an embodiment includes a first chip and a second chip. The first chip includes a first semiconductor element layer having a pixel region having pixel circuits and a peripheral region and a first wiring structure including a first wiring layer. The second chip includes a second semiconductor element layer having an electric circuit and a second wiring structure. The first and second chips are stacked, and have a trench extending through the first semiconductor element layer and having a pad through which a reference potential is supplied to the pixel circuits. The first wiring layer includes a first wiring pattern to which the reference potential is supplied. In plan view, the first wiring pattern located in a region aligned with the pixel region has a higher wiring density than the first wiring pattern located in a region aligned with the peripheral region.
