NOVELTY - The flooring (10) has an accommodation recessed part (13) for accommodating latent heat storage material (17) in a back surface (11b). An absorbing barrier (15) absorbs a part of the heat storage material to restrain that the heat storage material oozes out a side wall of the accommodation recessed part from a butt end of an edge of wood type base material (11). The absorbing barrier is formed by providing a groove part (12b) such that the accommodation recessed part is surrounded. Sheet material (19) with impermeability is positioned with respect to the heat storage material.    USE - Wood type flooring for heating a floor surface by using a heat source e.g. warm water pipe and electric heater.    ADVANTAGE - The latent heat storage material can be easily integrated in the wood type base material without using the container, which accommodates the latent heat storage material such that excavation of the accommodation recessed parts can be made small and floor strength can be improved. The latent heat storage material is in direct contact with a wall surface of the segmentation accommodation recessed parts, so that efficiency of thermal storage of a floor can be improved. The absorbing barrier absorbs the part of the heat storage material to restrain that the heat storage material oozes out the side wall of the accommodation recessed part from the butt end of the edge of wood type base material, so that the flooring can be thermally stored more uniformly, thus improving thermal storage performance of the flooring.    DETAILED DESCRIPTION - The sheet material is an oil proof sheet.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a wood type flooring by a side of a floor surface and an exploded perspective view of a wood type flooring at a back surface side.
