PROBLEM TO BE SOLVED: To provide: a bichrome molding including a MW-CNT-added foam for, by adding an appropriate quantity of multilayer carbon nanotubes (MW-CNT) to a site(s) of an insulating plastic material on which electroconductivity should be conferred, selectively modifying the added site(s) to be electroconductive; and a method for manufacturing the same.SOLUTION: Expanded beads are provided as PS foam particles having diameters of approximately 3 to 9 mm, and MW-CNT-containing PS foam particles are prepared by mixing a desired quantity of MW-CNT with the PS foam particles so as to confer electroconductivity thereon. Regions where electroconductivity are desired are molded by using, as a raw ingredient, the MW-CNT-containing PS foam particles, and regions where the maintenance of a high insulating capacity is desired are molded from MW-CNT-free PS foam particles alone. As a result, it becomes possible to manufacture a resin molding in which electroconductive regions 12 including the MW-CNT at an appropriate ratio and non-electroconductive (insulating) regions 10 including no MW-CNT and molded from PS alone coexist arbitrarily. |
