1. A detection device comprising:
a substrate;
an anode electrode provided on the substrate;
a cathode electrode that is provided on the same layer as that of the anode electrode and is adjacent to the anode electrode; and
an organic semiconductor layer that has a structure in which a p-type semiconductor layer and an n-type semiconductor layer coexist and that is provided so as to cover the anode electrode and the cathode electrode, wherein
the organic semiconductor layer covers both side surfaces and a top surface of the anode electrode and both side surfaces and a top surface of the cathode electrode.
