1. A photoelectric conversion element, comprising:
a first substrate;
an output extraction terminal part comprising a plurality of micropores;
a first transparent electrode disposed on the first substrate;
a hole-blocking layer disposed on the first transparent electrode;
an electron-transporting layer disposed on the hole-blocking layer;
a hole-transporting layer comprising a hole-transporting material; and
a second electrode disposed on the hole-transporting layer,
wherein the output extraction terminal part has an exposed area of the first transparent electrode through the plurality of micropores configured to extract electricity out from the photoelectric conversion element,
wherein the plurality of micropores are formed in the hole-blocking layer, and the plurality of micropores pierce through the first transparent electrode to reach the first substrate, and
wherein openings of the plurality of micropores are circular shapes, a ratio of an average diameter of the micropores to an average pitch of minimum distances between the adjacent circular micropores is 31.8% or more and 60% or less, and the average pitch is 20 μm or more and 60 μm or less, and
wherein an average thickness of the first transparent electrode is 10 urn or greater but 1,000 nm or less.
