PROBLEM TO BE SOLVED: To provide a technique for insert molding, where a hollow-shaped part is set in a cavity, to conduct the molding so as not to cause deformation of the part by a simple mechanism. SOLUTION: The method comprises the steps of: putting a hollow-shaped part 3 with an opening in the cavity 2 of a mold; filling a liquid into the hollow part of the hollow-shaped part 3; charging a molten material into the gap between the outer wall of the part and the inner wall of the cavity 2 in a state that the opening is sealed. Hence, a molded product with a high added value is obtained, which has a double-layer structure of different materials, and has a visual effect not available by conventional molding methods.
