PROBLEM TO BE SOLVED: To provide a mold for molding which can manufacture a number of foamed urethane roll from one mold for molding and a method for manufacturing the foamed urethane roll using the mold for molding by avoiding various problems which can be generated when a urethane raw material obtained by a mechanical frothing method or the like is injected into the mold for molding by a flow restricting member. SOLUTION: In the mold 12 for molding equipped with at least one cylindrical cavity 22 used under a standing condition and an opening part 22a on an upper part and an injecting hole 18 which is opened in the neighborhood of the bottom part and allows to inject the urethane raw material, the flow restricting member 16 which elevates its inner pressure accompanying with feeding the urethane raw material and restricts filling of the urethane raw material, is provided at a required position of the cylindrical cavity 22.
