<p>A granulated powder includes secondary particles obtained by granulation such that a plurality of metal particles in a metal powder are bound to one another by an organic binder and an outer coating layer provided so as to cover the surfaces of the secondary particles. The outer coating layer is formed of a low water-soluble material having a lower water solubility than the organic binder. The material having a lower water solubility than the organic binder is preferably any of an organic amine or a derivative thereof, and an acrylic resin. Further, the outer coating layer is preferably at least partly in contact with the surfaces of the metal particles at an interface with the secondary particle.</p> |
