Is adopted. Ease of production of them, Considering the manufacturing cost and the like, glass fiber reinforced cement is preferred, since the bending strength to 180 N / cm2 without employing a of about 230N / cm2, a conventional wood based It exhibits the same robustness as a plate material, for example, a particle board, and does not bend or generate floor noise. The thickness may be, for example, about 10 mm to 20 mm. In the case of a conventional wood substrate, there are cases where slits are formed from the lower surface. Similarly, if a large number of slits are formed from the lower surface over a depth of 1/2 to 2/3 of the thickness. The diffusion of sound, that is, vibration, can be further suppressed.
