PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane foam having high foam strength and low rebound resilience. SOLUTION: The polyurethane foam having density of 0.1 g/cm 3 or more contains a polyol A, which is a polyester-polyol having a hydroxyl value of 45-115 mg KOH/g and being obtained by polycondensing a polyhydric alcohol component containing a polyhydric alcohol having a side chain and a polybasic acid component, and polyol B, which is a polyether-polyol having 3 functional groups and a hydroxyl value of 15-40 mg KOH/g. The method of producing the polyurethane foam comprises reacting a polyol component, in which the weight ratio of polyol A to polyol B is 1.2-3, with a polyisocyanate component.
