Abstract: The present invention relates to a decoration technique for providing iridescent color effects or glittering luster effects to a resin casing by attaching a polarizing film in contact with a resin casing, and for finishing a cut-off edge portion of the polarizing film smooth. After forming the polarizing film on a mold having a prescribed shape, a thermoplastic resin is injected into the mold to produce a thermoplastic resin casing to which the polarizing film is firmly attached. When cutting off an excess portion of the polarizing film by using a cutting die, a heater built into the cutting die is energized, and the cut-off edge portion of the polarizing film is fused by the heating of the cutting die, thus fixing the edge portion to the thermoplastic resin.
