Abstract: In a method for producing a resin molded body, a thermosetting resin member is formed by heating a thermosetting resin material that is a raw material of the thermosetting resin member to complete a curing. A nascent surface having a functional group is formed on at least a part of a sealed surface of the thermosetting resin member by removing a surface layer that is an outermost layer of the sealed surface via irradiation of laser light to the sealed surface. The sealed surface of the thermosetting resin member is sealed with the thermoplastic resin member by injecting a thermoplastic resin material to the thermosetting resin member having the nascent surface, the functional group of the nascent surface being chemically bonded to the functional group of the additive. The thermosetting resin member has an absorption of the laser light at or above 10% per 1 μm.
