The organic binder contains polyvinyl alcohol or a derivative thereof and a polyol. Further, the ratio of the apparent density of the granulated powder to the true density of the metal powder (a metal material constituting the metal powder) is from 20% to 50%. Further, as the polyol, glycerin is preferred, and the addition amount thereof is preferably from 0.01 to 0.2 parts by weight based on 100 parts by weight of the metal powder.
