PROBLEM TO BE SOLVED: To provide a hydroxy group-containing phosphazene compound which can enhance the flame retardance of resin molded products and hardly deteriorates the mechanical characteristics and reliability of the resin molded products at high temperature. SOLUTION: Provided is the hydroxy group-containing cyclic phosphazene compound represented by formula (1), wherein, (n) is an integer of 3 to 8; A is a group selected from the group consisting of the following A1 group, A2 group, and A3 group, and at least one of 2n A groups is the A3 group. A1 group: a 1-8C alkoxy group which may be substituted with a 1-6C alkyl group or the like. A2 group: a 6-20C aryloxy group which may be substituted with a 1-6C alkyl group or the like. A3 group: at least one selected from the group consisting of 2-methyl-4-hydroxy-phenyloxy group, 3-methyl-4-hydroxy-phenyloxy group and 4-hydroxy-3,5-dimethyl-phenyloxy group.
