PROBLEM TO BE SOLVED: To provide coated white boards that cause no defects, for example, streak, scratch and the like, when they are coated their surfaces through the bent blade method and has excellent face quality, gloss and the like. SOLUTION: At least three layers, namely the front layer, the middle layer and the back layer of the paper are formed simultaneously and laminated and the front layer and the back layer are coated with the primary coating on their outer surfaces. The resultant under-coated paper is used the base paper, and the base paper is coated with the coating liquid of high share viscosity of 70-120 mPa.s by means of the bent blade coater with <=0.4 mm thick chromium-plated blade at a coating speed of 400 m/min whereby the objective coated white boards are produced.
