Article made of biodegradable resin and method of making the same

摘要

An article includes a base (25) or body made of a biodegradable resin. The article allows the base (25) to have the surface covered with a coating film (26) containing a conductive material. The coating film (26) firmly attaches to the surface of the base (25), This results in a reliable establishment of an electric conductivity of the article. The coating film (26) functions as a shield for electromagnetic waves, a ground, and the like. Sandblast may be employed to remove the coating film (26) off the surface of the base (25). The base (25) can be decomposed in the ground. Refuse can thus be decreased to the utmost. Even when the base (25) is incinerated, the amount of carbon dioxide can be reduced to approximately half the amount obtained in the case of a base (25) made of a petroleum resin material.
