PROBLEM TO BE SOLVED: To provide a blade coating method realizing stable coating of a coating liquid by a simple apparatus constitution, and a disc coating method using this, and to realize formation of a coating liquid layer having a good surface property by preventing dropping of the liquid and generation of a streak on a coating surface. SOLUTION: In the blade coating method, a mask 25 having an opening 27 is superposed on an optical disc D, the coating liquid 49 is fed onto the mask 25, the mask 25 and the optical disc D are left from each other after the mask 25 is coated with the coating liquid 49 by a blade 51 relatively moved relative to the mask 25 above the mask 25 and the coating liquid layer 65 corresponding to the opening 27 of the mask 25 is formed on the optical disc D. A clearance G of the mask 25 and a lower surface 59 of the blade 51 is made to 20μm-150μm and is made to 10%-50% of film thickness T of the coating liquid layer 65 applied on the optical disc D.
