快適な住環境を得ることができるものである。Further, since the floor base material of the present invention has a cushioning body laminated on the lower surface of the lower plywood, when used as a floor base material, even if there is unevenness on the lower ground of the floor board due to unevenness, the cushioning body will have the unevenness. It absorbs and keeps the floor surface always flat, which makes it possible to finish the floor with a beautiful appearance, and also provides a moderate cushioning effect. In addition, as mentioned above, the strength of the hood is large, so the corn well withstands the heavy load generated on the corn by sinking the cushion when a load is applied, and it does not break, so it is a thick and soft cushion. It becomes possible to use the body,
A comfortable living environment can be obtained.
