A polylactic acid foam obtained from a resin composition comprising polylactic acid (A), a polyolefin resin (B), and a polyolefin resin copolymer (C), characterized in that the ratio of the weight of the polylactic acid (A) to the total weight of the polyolefin resin (B) and the polyolefin resin copolymer (C), (A)/{(B)+(C)}, in the resin composition is 0.2-6. The polylactic acid foam is a foam made from a polylactic acid resin, which burdens the environment little, and excellent in heat resistance, moldability, and compression recovery. This polylactic acid foam is suitable for use in various applications where polyolefin resin foams are used at present, such as automotive applications, bases for heat insulators, cushioning materials, packing materials, pressure-sensitive adhesive tapes, etc., and joint filling materials. |
