A photoelectric conversion apparatus includes, on one substrate, a pixel driving unit and a signal processing unit that includes a digital circuit configured to execute signal processing. A first voltage and a second voltage different in value from the first voltage are supplied to the digital circuit of the pixel driving unit. A third voltage and a fourth voltage different in value from the third voltage are supplied to the digital circuit of the signal processing unit. A main portion of a first conductor that supplies the first voltage to the digital circuit of the pixel driving unit and a main portion of a second conductor that supplies the third voltage to the digital circuit of the signal processing unit are isolated from each other. |
