The present invention provides a photo-cationic polymerizable composition being photo-curable, especially being polymerized and cured upon being irradiated with visible light (380ˆ¼500 nm), superior in physical properties when cured and further superior in storage stability before being polymerized and cured. A photo-cationic polymerizable composition comprising the following ingredients as essential ingredients: (A) 100 parts by weight of a cationic-polymerizable compound, (B) 0.01 to 10 parts by weight of an acid generator selected from the group consisting of aromatic iodonium salts and aromatic sulfonium salts, (C) 0.01 to 10 parts by weight of a benzoyl compound having a hydroxy group and (D) 0.01 to 10 parts by weight of a thioxanthone type radical generator.
