Abstract
Provided is a photodetection device capable of suppressing an increase in a parasitic capacitance of an electrode pad. A photodetection device includes: a first semiconductor layer that includes a photoelectric conversion unit and has one surface being a light incident surface and another surface being an element formation surface; an insulating layer laminated on a side of the light incident surface of the first semiconductor layer; an electrode pad exposed from a surface of the insulating layer on a side opposite to a surface on a side of the first semiconductor layer in a state where the insulating layer is interposed between the electrode pad and the first semiconductor layer; and an insulating ring that is a ring having an insulating property, penetrating the first semiconductor layer in a thickness direction, and surrounding the electrode pad in a plan view.
