(57) [Summary] An object of the present invention is to provide a wood cement board whose dimensional stability is greatly improved and coating film adhesion is good. SOLUTION: A cement-based inorganic material, a wood reinforcing material, A raw material mixture containing mica having an average particle size of 100 μm or more and an aspect ratio of 60 or more is dispersed in water to form a raw material slurry, and a papermaking mat is formed, and the papermaking mat is pressed and autoclaved at a temperature of 160 ° C. or more. This makes the mica surface rough, enhances the bonding between the mica, and secures the adhesion to the coating film. |
