<P>PROBLEM TO BE SOLVED: To provide an insulated coating method and an insulator which can contribute to global environment conservation in insulating treatment of a conductive member of voltage apparatus and have sufficient durability (for example, strength and degradation resistance) and electric characteristics after performing a heat-cycle. Ž<P>SOLUTION: A high-polymer composition obtained by adding and kneading silica powder to a high-polymer material which is a living thing-originated material (biodegradable resin) as a base material is attained. The high-polymer composition is made to a biopolymer compound, and a living thing-originated insulating member is coated to an insulated section of the conductive member by powder-coating insulating powder obtained by making the biopolymer compound into fine particles to the conductive member of voltage apparatus.
