NOVELTY - Dispersion liquid formed by dispersing the particles of single-crystal material of multiple-oxide salt to dispersion medium, is coated on electrode (3) which is supported on base material (2), to form liquid film. Then, liquid film is heated, and dispersion medium is removed by volatilization, to form electron carrying layer (4). Then, pigment layer (D) is formed on the electron carrying layer. Another electrode (6) is formed facing the electrode (3) through electron carrying layer and pigment layer. Thus, photoelectric transducer is formed.    USE - Manufacture of photoelectric transducer for dye-sensitized solar cell used for electronic devices (claimed) such as calculator and mobile phone including personal handy-phone system (PHS). Can also be used for light receiving elements such as photosensor and optical switch.    ADVANTAGE - The electron carrying layer in the photoelectric transducer has excellent electron transferring property. Photoelectric transducer has high photoelectric conversion efficiency. A reliable electronic device is provided using the transducer.    DETAILED DESCRIPTION - Dispersion liquid formed by dispersing the particles of single-crystal material of multiple-oxide salt to dispersion medium, is coated on an electrode (A) which is supported on a base material, to form a liquid film. Then, liquid film is heat-processed at a temperature below the tolerable temperature limit of resin material on liquid film, and the dispersion medium is removed by volatilization, to form an electron carrying layer. Then, a pigment layer is formed on the electron carrying layer. Another electrode (B) is formed facing the electrode (A) through electron carrying layer and pigment layer. An electrolyte layer (5) is formed between two electrodes. Thus, photoelectric transducer is formed. The single-crystal material of multiple-oxide salt has layered structure, tunnel structure or perovskite structure. The multiple-oxide salt includes niobium, titanium, zinc, tin, vanadium, indium, tungsten, tantalum, zirconium, molybdenum and/or manganese. The multiple-oxide salt is preferably potassium niobate (K4Nb6O17, K2Nb8O21) or sodium titanate (Na2Ti3O7, Na2Ti6O13). The electrode (A) essentially contains metal-oxide material.
