Abstract: Provided are a foam molded body capable of improving damping properties and sound insulation properties of a panel and realizing weight reduction of a panel, a dam rubber, a complex of a dam rubber and a panel, and a method for increasing a sound transmission loss.The present invention is concerned with a foam molded body of a resin composition containing a block copolymer (I) which is a block copolymer having a polymer block (A) composed mainly of a structural unit derived from an aromatic vinyl compound and other polymer block (B), exhibits a peak top temperature of tan δ, as measured under a condition of a thickness of a test piece of 1 mm, a strain amount of 0.1%, a frequency of 1 Hz, a measurement temperature of −70 to 70° C., and a temperature rise rate of 3° C./min in conformity with JIS K7244-10 (2005), of −50 to 50° C., and has a peak top molecular weight determined in terms of standard polystyrene by gel permeation chromatography of 30,000 to 500,000; at least one olefin-based polymer (II) selected from the group consisting of an ethylene-propylene-diene copolymer rubber, an ethylene-vinyl acetate copolymer, and a polyethylene-based resin; a crosslinking agent (III); and a foaming agent (IV).
