PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane foam having low resiliency and improved mechanical strength and flexibility. SOLUTION: The method for producing the polyurethane foam comprises reacting a polyol component with a polyisocyanate component in the presence of a polyalkylene chain-containing compound represented by formula (I) (wherein R is a residue of an n-valent polyalkylene-polyol, an n-valent polyalkylene-ether-polyol, or an n-valent polyalkylene-ester polyol; and n is 2 or 3).
