The woody base material 11 has a dimensional variation per 1% water content change that is larger than 0.02% and has an average water content that is 6 to 10 mass%. The moisture-proof film 20 has a moisture permeability that is equal to or lower than 7 g/m24 hr. On a surface on the decorative sheet 1's side are formed a plurality of salients 5. Each salient 5's height is within a range equal to or larger than 20 μm and equal to or smaller than 80 μm. A circle obtained by converting area of each salient 5 in a plan view to a circular shape has a diameter within a range equal to or larger than 40 μm and equal to or smaller than 200 μm. The plurality of salients 5 are randomly arranged so that a rate of area, per unit area in a plan view, occupied by the plurality of salients 5 is within a range equal to or larger than 0.05 and equal to or smaller than 0.5.SELECTED DRAWING: Figure 1
