NOVELTY - The dye-sensitized photoelectric conversion element (10) has an electrolyte layer (8) that is located between a porous electrode (7) and a Counter electrode (1). An electroconductive diamond-like carbon film (4) is positioned on a metal substrate (2). A catalyst layer (3) is formed on the electroconductive diamond-like carbon film. A sealing layer (9) is formed of UV cured resin and a thermosetting resin, provided to seal the electrolyte of an electrolyte layer and adhered with the electroconductive diamond-like carbon film.    USE - Dye-sensitized photoelectric conversion element e.g. solar cell used for electronic device and building (all claimed). Uses include but are not limited to mobile telephone, mobile device, robot, personal computer, vehicle equipment, domestic electrical appliance, apartment, church, factory, warehouse school building, government building, stadium etc.    ADVANTAGE - The photoelectric conversion performance and time-lapse durability of the photoelectric conversion element can be enabled at low cost. Highly efficient electronic device can be realizable by using the photoelectric conversion element. The time-dependent change of the counter electrode can be suppressed for a long period of time. The fall of the open circuit voltage for a long time and decline in photoelectric conversion efficiency can be suppressed. The low electrically resistant solution liquid can be used for the metal substrate. The binding property of the sealing layer and the metal substrate can be improved. The time-independent deterioration of the dye-sensitized photoelectric conversion element can be suppressed.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a manufacturing method of photoelectric conversion element;    (2) a building; and    (3) an electronic device.
