The acetylated wood fiber is charged into a reaction tank to bring an oxygen gas entrained by an ozone generated by an ozone generator into contact with the wood fiber and obtain the ozone-oxidized wood fiber. Further, a binder resin such as a modified melamine is applied to the ozone-oxidized wood fiber by a spray process and the wood fiber is molded into a mat by a foaming process and then is molded in the form of a plate by heating it under pressure. After that, these plates are laminated to obtain a wood fiber laminated board.  Thus the wood fiber laminated board shows the high resistance to water absorption and moisture and superb dimensional stability and outstanding strength.
