PROBLEM TO BE SOLVED: To achieve the sealing of an interface between a first molded body made of thermoset resin and a second molded body made of thermoplastic resin without applying seal materials after the molding of the second molded body.SOLUTION: The sealing of an interface is performed in the following procedures: preparing a first molded body 13 in which a photoresponsive compound whose phase transition from a solid phase to a liquid phase is performed by ultraviolet irradiation, and whose phase transition from the liquid phase to the solid phase is performed by visible light irradiation or heating exists on a surface 13b; making the photoresponsive compound into the liquid phase by ultraviolet irradiation by irradiating the surface 13b of the first molded body 13 with ultraviolet rays; injecting liquid thermoplastic resin into a molding die in a state where the first molded body 13 is installed in the molding die, and bringing it into contact with the surface 13b of the first molded body 13, and solidifying the liquid thermoplastic resin to form a second molded body 20; and performing visible light irradiation or heating to the surface 13b of the first molded body 13 brought into contact with the second molded body 20 to perform the phase transition of the photoresponsive compound from the liquid phase to the solid phase. |
