Disclosed is a foam containing a polylactic acid resin (a), at least one thermoplastic resin (b) selected from polyolefin resins and polystyrene resins, and a block copolymer (c) of a vinyl aromatic compound and a conjugated diene. The weight ratio (a/b) between the component (a) and the component (b) is from 80/20 to 20/80. The foam contains 0.5-20 parts by weight of the component (c) per 100 parts by weight of the total of the components (a) and (b).
