Abstract:
PROBLEM TO BE SOLVED: To provide a decorative material for flooring having weather-proofness while inhibiting occurrence of a warp or drawn bending based on a moisture atmosphere even when using, as a woody base material, a woody base material having a dimensional variation per 1% water content change, the dimensional variation being larger than 0.02%.SOLUTION: A decorative material for flooring 10 includes a decorative sheet 3 provided on one face of a woody base material 1 and a moisture-proof film 2 on the other face. The woody base material 1 has a dimensional variation per 1% water content change that is larger than 0.02% and has an average water content that is within a range of 6 to 10 mass%. The moisture-proof film 2 has a moisture permeability that is equal to or lower than 1.0 g/m24 hr.
