<P>PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin foam excellent in thermal fusability and moldability. <P>SOLUTION: The polylactic acid-based resin foam includes a polylactic acid-based resin and an acrylic resin, wherein the polylactic acid-based resin is contained in a proportion of >50 parts by weight and ≤90 parts by weight based on 100 parts by weight of the total of the polylactic acid-based resin and the acrylic resin; the polylactic acid-based resin foam has a crystallization peak temperature of 85 to 115°C, which is originated from the polylactic acid-based resin; the crystallization peak temperature is higher by 10 to 40°C than an intrinsic crystallization peak temperature, which is originated from the polylactic acid-based resin; and the polylactic acid-based resin foam satisfies (I): 0.1≤F<SB POS="POST">pla</SB>/F<SB POS="POST">ac</SB>≤2.5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
