PROBLEM TO BE SOLVED: To provide a building material for a floor for stabilizing quality, by reducing a manufacturing process, by stably producing a desired color tone.SOLUTION: A building material for a floor is formed by laminating a thermoplastic resin molding on a woody base material, and is formed by blending paper powder of 15-60 wt.% and a coloring pigment of 0-10 wt.% in the thermoplastic resin molding, and is also formed by laminating a decorative sheet on a surface of the thermoplastic resin molding. Since high-degree processing is applied to paper in the processing stage thereof without including wood flour being a natural object, a stable color-tone quality can be secured by blending the paper powder of using this as a raw material. |
