Resin molded article and production method thereof

Abstract

An adhesive as a heat resistant rubber-based adhesive is applied to a region (peripheral region) of integration of a metal sheet (Al sheet) and a resin and to a region (peripheral region) of integration of a fiber sheet (CF sheet) and a resin. The metal sheet and fiber sheet are temporarily fixed to dry the adhesive, then, the joined article is accommodated in an injection molding machine, a polycarbonate resin is injected, and the joined article (metal sheet and fiber sheet) is integrally molded with the polycarbonate resin.
