Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a basket type silsesquioxane copolymer having a basket type silsesquioxane skeleton containing a curable functional group and aromatic ring, and to provide a method for production of the copolymer whose structure can be easily controlled.SOLUTION: There is provided a method for producing a basket type silsesquioxane copolymer by polymerizing a basket type silsesquioxane resin (A) represented by general formula (1): [RSiO][RSiO][RSiO](wherein Ris an unsaturated bond-containing group; and Ris an epoxy-containing group) and an aromatic diol compound (B) at 100-140°C in the presence of at least one polymerization catalyst (C) selected from the group consisting of compounds of tertiary amine, quaternary ammonium, tertiary phosphine and quaternary phosphonium.
