The composite molded body obtained by bonding the film (1) and the resin layer (2) of the present invention has superior strength, excellent pliability, and large toughness in all directions. Further, the composite molded body obtained by bonding the film (1) and the fiber-reinforced resin layer (3) has both an extremely large impact resistance which could never be obtained with conventional molded bodies and also a strength and modulus greater than in the past. The molded body can be suitably used for aerospace equipment, sports goods, leisure goods, etc. making use of its light weight, corrosion resistance, and other properties in addition to the above superior proportion.
