An optical/electrical conversion element used for a photosensor or a solar battery. An optical/electrical conversion layer, composed of an assembly of a light-absorbing dendrimer structure ( 1 ), operating as an electron donor, and fine metal particles ( 2 ), operating as an electron receptor, are self-collectively formed by imparting chemical affinity to the dendrimer structure and to the fine metal particles. With the present optical/electrical conversion element, in which the light-absorbing substance has a dendrimer structure, the electrons, excited on light absorption, migrate over a long distance via molecular chain to get to the fine metal particles ( 2 ) operating as an electron receptor. The electrons are routed quickly to outside as current via contact among the fine metal particles and/or between the fine metal particles and an electrode.
