PROBLEM TO BE SOLVED: To provide a floor finishing material having a prescribed bending strength and water repellency, using a base material for a floor finishing material having same damage resistance or more as that of a floor finishing material of a MDF(medium density fiberboard) base material and same dimension stability or more as that of a floor finishing material of a plywood base material, and having superior flame retardancy and thermal conductivity in a sheet-form thermoforming body containing prescribed amounts of inorganic compound having endothermic degradability, cellulose fiber, inorganic fiber, and thermoplastic resin. SOLUTION: This base material for the floor finishing material comprises the sheet-form thermoforming body containing 50-90 mass% of the inorganic compound having endothermic degradability in solid, 2-27 mass% of the cellulose fiber in solid, 2-20 mass% of the inorganic fiber in solid, and 5-20 mass% of thermoplastic resin in solid. This base material is characterized in having 19 MPa or more in the bending strength (JIS A-5905) obtained by finding the average of the both measuring results in the fiber orientation direction and the direction orthogonally crossing therewith, 1-4 mm in the thickness, and the water repellency.
