PROBLEM TO BE SOLVED: To provide a production method of a resin molding in which production can be performed by small processes in the resin molding produced by using a mold, and excellent strength and adiabaticity are possessed; and the resin molding.SOLUTION: Provided is a production method of a resin molding 10 in which a thermosetting resin composition is supplied between molds that mutually counter up and down to be molded. A first thermosetting resin composition including: a thermosetting resin including a monomer or an oligomer having volatility; a radical polymerization initiator; and an inorganic filler as essential components, and a second thermosetting resin composition are used, a cure rate of the first thermosetting resin composition is adjusted to be faster than a cure rate of the second thermosetting resin composition, the first thermosetting resin composition is supplied into one mold side of the molds that counter up and down, and the second thermosetting resin composition is supplied into the other mold side, molds are heated, thereby a foam layer 2 is formed at a central part of the resin molding 10 or an intermediate of a mold side in which the first thermosetting resin composition is supplied. |
