摘要：
A resin foam having fine foam cells is provided at low cost. A method of producing the foam includes preparing a molten resin composition and continuous extrusion foaming of the molten resin composition. The molten resin composition is prepared by melting a resin mixture of resins (A) and (B) by dissolving a foaming agent into the resin mixture. Resins (A) and (B) respectively have appropriately selected glass transition temperatures and resin (B) particles of appropriate diameter are dispersed in resin (A).
