This invention provides a precoated metal plate that can prevent the occurrence of defects in an optical disk, and, at the same time, can maintain high peel strength of an adherend to a resin film, and can realize easy adhesion of the adherend to the surface of the resin film. The precoated metal plate comprises a metal plate and a resin film provided on the surface of the metal plate. The resin film comprises an epoxy resin matrix layer and soft beads dispersed in the epoxy resin matrix layer. For the soft beads, the compressive strength at single bead 10% deformation by a microcompression test is not more than 10 MPa. The content of the soft beads is not less than 5% by mass and not more than 50% by mass based on the epoxy resin matrix layer, and the average particle diameter of the soft beads is not less than 1.1 times and not more than 5 times the average thickness of the epoxy resin matrix layer.
