PROBLEM TO BE SOLVED: To provide a photoelectric conversion element superior in durability.SOLUTION: A photoelectric conversion element 100 comprises a photoelectric conversion cell 90 including an electrode substrate 10, a counter substrate 20, an annular sealing part 30 and an electrolyte 40. The sealing part is glued to the electrode substrate, and includes: an annular first resin sealing part 70 including a thermoplastic resin; and an annular second resin sealing part 80 including a thermoplastic resin, and provided so that the counter substrate is sandwiched by the second resin sealing part together with the first resin sealing part. The second resin sealing part has a melting point higher than that of the first resin sealing part. The first resin sealing part has: a first body portion glued to the electrode substrate; and a first convex portion provided on a side of the first body portion, opposite to the electrode substrate. The first body portion has: an insertion part inserted between the electrode substrate and the counter substrate; and a non-insertion part which is not inserted between the electrode substrate and the counter substrate. The first convex portion is provided on the non-insertion part of the first body portion. The second resin sealing part has a second body portion provided on a side of the counter substrate, opposite to the electrode substrate. The second body portion of the second resin sealing part is glued to the first convex portion.SELECTED DRAWING: Figure 1 【課題】優れた耐久性を有する光電変換素子の提供。【解決手段】光電変換セル９０が、電極基板１０と対向基板２０と環状の封止部３０と電解質４０とを備え、封止部が電極基板に接着され、熱可塑性樹脂を含む環状の第１樹脂封止部７０と、第１樹脂封止部とともに対向基板を挟むように設けられ、熱可塑性樹脂を含む環状の第２樹脂封止部８０とを有し、第２樹脂封止部が第１樹脂封止部よりも高い融点を有し、第１樹脂封止部が電極基板に接着される第１本体部と、第１本体部のうち電極基板と反対側に設けられる第１凸部とを有し、第１本体部が電極基板と対向基板との間に挿入される挿入部と、電極基板と対向基板との間に挿入されない非挿入部とを有し、第１凸部が第１本体部の非挿入部に設けられ、第２樹脂封止部が対向基板のうち電極基板と反対側に設けられる第２本体部を有し、第２樹脂封止部の第２本体部が第１凸部に接着されている光電変換素子１００。【選択図】図１
