A polyurethane foam is obtained by foaming a mixture that includes polyol and polyisocyanate. The polyol comprises a polycarbonatediol having a polyester structure, and a polycarbonatediol obtained by performing a polymerization reaction using a 1,5-pentanediol and a 1,6-hexanediol. The polyurethane foam is characterized by having a density of 0.1-0.4 g/cm3. |
