Claim 4:
5. A photodetection element comprising;
a first electrode having the electrode structure and a second electrode; and
as the element, at least one magnetic element disposed between the first electrode and the second electrode, the at least one magnetic element including a first ferromagnetic layer, a second ferromagnetic layer and a spacer layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer, wherein
the electrode structure comprises:
a metal film with an opening formed in a part of the metal film; and

a transparent conductive film disposed in the opening, wherein
the transparent conductive film is electronically connected to the at least one magnetic element and overlaps with the at least one magnetic element as viewed in a plan view in a thickness direction of the transparent conductive film, and the transparent conductive film is configured to be irradiated with light.
