A composite molded article of light weight and low cost, and producing method thereof, and also, an inner mold and a metal mold which are used for producing a cellular molded article in mold pattern having surface skin and capable to be preheated even in a condition of opening the metal mold so that the molding cycle can be shortened. Composite molded article 1 which is composed of cellular molded article 2, surface skin material of thermoplastic resin 3 and at least one kind of surface skin material 4 which is adhered on surface 3a of this surface skin material of thermoplastic resin 3. A producing method of composite molded article 1 that, on either one of metal mold A or B which composes mold pattern C, surface skin material of thermoplastic resin 3 is placed, and after clumping, by an expansion molding in this mold pattern 7, cellular molded article in mold pattern 2 to be formed and surface skin material of thermoplastic resin 3 are melt united to one piece, wherein, before placing surface skin material of thermoplastic resin 3, at least one kind of surface skin material 4 is placed on one of metal mold A in advance, and at the same time or before then, these surface skin material of thermoplastic resin 3 and surface skin material 4 are melt united to one piece.
