<p><P>PROBLEM TO BE SOLVED: To provide a biodegradable resin molded article which is molded from a biodegradable resin material, but certainly has conductivity. <P>SOLUTION: This biodegradable resin molded article 14 is characterized by comprising a main body 25 formed from a biodegradable resin material and a coating film 26 covering the surface of the main body 25. In the biodegradable resin molded article 14, the coating film 26 is sufficiently adhered to the surface of the main body 25. Conductivity is surely established in the biodegradable resin molded article 14. The coating film can act as an electromagnetic wave shield or an earth. The coating film 26 can simply be peeled from the surface of the main body, for example, on the basis of sand blasting. After the peeling, the main body 25 can be degraded, for example, in soil. The production of wastes is avoided as much as possible. When the main body is burned, the production of carbon dioxide is reduced to an amount of an approximately half based on that on the combustion of an oil-based resin material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
