    摘要: A resin composition containing thermoplastic resin and a flame retardant is sufficiently kneaded and molded, and carbon dioxide in a supercritical state is caused to permeate into the resin composition. Subsequently, the resin composition is degassed by cooling and/or pressure reduction. As a result of degassing, a resin foam body having a fine and uniform micro-cellular foam structure is obtained. The resin foam body has a cyclic structure in which a resin phase and a pore phase are continuous and intertwined. The obtained resin foam body can suitably find applications such as home OA parts, electric and electronic parts and automobile parts that are required to be highly strong, lightweight and nonflammable.
