PURPOSE: To make small a space between adjacent plate members by connecting sides of long strip-shaped woody plate members with soft joints over the longitudinal length in the front side from the central part in the thick direction.

CONSTITUTION: Long strip-shaped woody plate members 1 sticking cushion sheets 2 on the rear sides connect their sides with soft joints 3 over the longitudinal length in the front side from the central part in the thick direction to form a woody carpet. A chamfering section 5 over the longitudinal length is provided to a corner section on the rear of a side in each of the woody plate members 1 and is laid on the floor ground such as concrete, concrete panel, etc. Then, when the wooden carpet is bent with the rear as the inside, the soft joints 3 are bent, and sides of adjacent woody plate members 1 are smoothly bent by the chamfering section 5 without running against each other. Accordingly, even if the woody carpet is bent, a cushion material is expanded, and the incursion of dust, etc., into the carpet through the space can be prevented.
