PROBLEM TO BE SOLVED: To provide a tatami mat having high impact absorption properties and durability.SOLUTION: A core material for a tatami mat includes an elastic body 1A, a first core material 2 that is superposed on a top surface of the elastic body 1A, and a second core material 3 that is superposed on an undersurface of the elastic body 1A. The elastic body 1A comprises a mesh corrugated sheet 11 that has a net-like synthetic resin plate molded in a corrugated shape in a thickness-direction cross-section, a first liner sheet 12 that is bonded to a top surface of the mesh corrugated sheet 11, and a second liner sheet 12 that is bonded to an undersurface of the mesh corrugated sheet.SELECTED DRAWING: Figure 1 |
