PROBLEM TO BE SOLVED: To avoid the surface of a wooden floorboard becoming slippery when a puddle or a wetting is generated due to a rain fall, dew condensation or water sprinkling and a dangerous condition such as a fall of a walker occurring, in all directions of lengthwise direction, square direction and the like of a board surface. SOLUTION: By means of using an endless blade intersecting at right angles with the lengthwise direction of a wood and bending a portion of the blade toward the board surface side or changing the shape of the blade, the depth of a point or a cut made in the board surface is changed to obtain the non-slip effects with high designedness. Further, a floor material enhanced in durability by subjecting a resin-impregnated reinforced wood to sliding processing or by subjecting an untreated material to non-slip treatment and performing painting or the like is provided.
