Abstract: Resin-impregnated decorative paper includes decorative paper impregnated with an impregnation resin, and the decorative paper includes a base paper, a pattern layer formed by printing on the upper side UP of the base paper, and a foamable resin layer stacked on the upper side UP of the pattern layer and containing a foaming agent. The foamable resin layer foams to expand in volume, thereby forming an uneven pattern on the upper UP surface of the pattern layer, and the uneven pattern has a maximum height of 20 μm or more and 90 μm or less in a vertical direction from a recess to a projection.
