PROBLEM TO BE SOLVED: To provide a contact composite material of a photocatalytically active inorganic oxide semiconductor and a conductive polymer, in which nitrogen-fixing efficiency is remarkably improved. SOLUTION: A composite photocatalytic material prepared by contact composition of the inorganic oxide semiconductor having a photocatalytic function and the conductive polymer which is soluble in a solvent or is dispersible in the solvent is irradiated with a light beam and, thereby, nitrogen gas in air is fixed as ammonium salt and ammonia. When bringing the conductive polymer material into contact with the photocatalytically active inorganic oxide semiconductor, a coating method for suppressing a decrease of the number density of oxygen defect parts performing nitrogen-fixing reaction is used.
