Abstract: A method for producing a composite material molded article, including laminating a fibrous filler on a mold; pressure-reducing inside an airproof space, the airproof space being formed with the mold laminated with the fibrous filler and an airproof film covering thereon; and impregnating a resin material in the fibrous filler, the formation of the airproof space including bonding the mold and the airproof film with a seal material containing a (meth)acrylic polymer as an adhesive. The composite resin molded article obtained by the method of the present invention can be suitably used in fields in which composite materials of fibrous fillers such as glass fibers and carbon fibers are generally used, for example, housings, structural members, and the like for moving objects or movable objects.
