摘要： A composite molded article in which another material is integrated on a face having grooves in a grooved resin molded article having grooves in which end parts of a fibrous inorganic filler protrude and are exposed from lateral faces of the grooves on a surface side in at least the insides of the grooves. Exposure of the end parts of the fibrous inorganic filler and formation of the grooves may be accomplished by laser irradiation, and the depth of the grooves may be at least 200 μm. Another molded article comprising the other material is arranged surrounding the fibrous inorganic filler in the insides of the grooves.

摘要： A resin molded article that has a high bond strength in a composite molded article in which a first molded article and a second molded article are integrated, and that has a stable and uniform bond strength of a composite molded article between shots of the molded article. The composite molded article includes a grooved first resin molded article containing at least a resin, a glass fiber, and a laser absorption material, and having grooves that expose the glass fiber; and a second molded article adjacently disposed on the grooved surface of the first resin molded article. In the first resin molded article, the glass fiber is added in an amount of 12-45 mass % with respect to the total mass of the resin composition that constitutes the resin molded article, the laser absorption material is added in an amount of 0.25-10 mass % with respect to the total mass of the resin composition, and the glass fiber and the laser absorption material are blended within specific blending ranges.
