Abstract: A material for molding according to an embodiment of the present disclosure is a material for molding containing cellulose fibers and a resin. The resin contains a binder and urethane fibers. The resin has a maximum 1 at a weight average molecular weight of 50,000 to 150,000 and a maximum 2 at a weight average molecular weight of 75,000 to 300,000 in a molecular weight distribution curve by a GPC method with chloroform as an eluate. An area value at the maximum 2 is smaller than an area value at the maximum 1.
