PROBLEM TO BE SOLVED: To provide a manufacturing method of a woody board capable of enhancing heat storage property compared to prior art without providing strength reduction of the woody board.SOLUTION: A latent heat storage material at a melting state is impregnated into a woody molded body 1a by impregnating the woody molded body 1a into a latent heat storage material 5a at a melting state so that a heat storage layer consisting of the latent heat storage material 5a is formed on a surface of a woody molded body 1a manufactured by collecting woody materials and compression molding the same to a board shape for covering a surface of the woody materials such as wood chips and the latent heat storage material 5a is impregnated inside of the woody materials such as wood chips in which the heat storage layer is formed. During impregnation of the latent heat storage material, impregnation of the latent heat storage material to the woody molded body 1a is conducted so that the heat storage layer is formed with network form in a woody board 1 from the front to the rear of the woody board 1.SELECTED DRAWING: Figure 1 【課題】木質ボードの強度低下を招くことなく、これまでのものに比べて蓄熱性を高めることができる木質ボードの製造方法を提供する。【解決手段】木質系材料を集積してボード状に加圧成形された木質成形体１ａに対して、木質片などの木質系材料の表面を覆うように表面に潜熱蓄熱材５ａからなる蓄熱層が形成されるとともに、蓄熱層が形成された木質片などの木質系材料の内部に潜熱蓄熱材５ａが浸透するように、溶融状態の潜熱蓄熱材５ａに前記木質成形体１ａを浸漬させて、木質成形体１ａに溶融状態の潜熱蓄熱材を含浸する。この潜熱蓄熱材の含浸において、木質ボード１の表面から裏面にわたって、木質ボード１内にネットワーク状に蓄熱層が形成されるように、木質成形体１ａへの潜熱蓄熱材の含浸を行う。【選択図】図１
