Abstract
In a laminated steel plate in which steel plates are joined to both faces of a core layer, the core layer is formed of a meshed wire group formed using wires in a mesh form and a resin sheet, the wires forming the meshed wire group have a tensile strength of 601 MPa or higher, and an opening of the meshed wire group is equal to or less than ten times the thickness of the steel plates. By thus defining the tensile strength of the wires, light-weightness can be achieved compatibly with high rigidity and shock resistance, and by defining the opening of the meshed wire group, workability and shape stability after being processed can be improved.
