Abstract
A photoelectric conversion apparatus is provided. The apparatus comprises a pixel region in which a plurality of pixels each including a photoelectric conversion portion and a charge holding portion formed in a substrate are arranged, and a peripheral region. Above the substrate, an electrically conductive layer including an electrode pattern for transferring charges in the photoelectric conversion portion to the charge holding portion, a wiring layer including a wiring pattern electrically connected to the electrode pattern, an interlayer film arranged between the wiring layer and the substrate, a metal layer arranged between the interlayer film and the substrate and arranged so as to cover at least the charge holding portion and the electrode pattern are provided. In the peripheral region, the metal layer covers at least an upper surface of an electrically conductive pattern included in the electrically conductive layer.
