[PROBLEMS] To form a sealing layer for sealing an electrolytic solution of a wet organic solar cell, which has excellent properties such as sealing property, resistance to an electrolytic solution, adhesive strength at high temperature, moisture permeability resistance, and screen printing suitability. To provide a suitable photocurable composition. At least one monofunctional (meth) acrylate selected from the group consisting of an aliphatic monofunctional (meth) acrylate having 15 to 26 carbon atoms and an alicyclic monofunctional (meth) acrylate having 15 to 26 carbon atoms. At least one polar group selected from the group consisting of mono (2-acryloyloxyethyl) succinate, mono (2-acryloyloxyethyl) hexahydrophthalate, and mono (2-acryloyloxyethyl) phthalate ( A photocurable composition containing a (meth) acrylate, a saturated thermoplastic elastomer, an alicyclic saturated hydrocarbon resin, and a photopolymerization initiator.
