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.

A laminated steel plate, comprising:
- a core layer including a wire group formed in a mesh form using wires and a resin sheet, and
- steel plates joined respectively to both faces of the core layer,
- wherein the wires have a tensile strength of 601 MPa or higher, and an opening of the wire group is equal to or less than ten times the thickness of the steel plates, and
- wherein a thickness of the core layer is 0.1 mm to 3.0 mm, and a thickness of the steel plates is 0.2 mm to 2.0 mm.
