SOLUTION: The pressure sensitive adhesive 40 is applied to the reverse surface of the woody base material 20 as a dot shape or broken line shape pressure sensitive adhesive reinforcement 41 in its longitudinal direction. The total area of the applied pressure sensitive adhesive 40 is set to about 0.8% to 7.5% of the reverse surface area of the woody base material 20.
