There is provided a coating method for forming a coat having a less unevenness in its thickness on a sheet-like substrate. In the method in which a coating liquid is continuously supplied from a supply head to a surface of a continuously traveling sheet-like substrate to form a coat while controlling its thickness by a coating bar disposed above the sheet-like substrate, the coating liquid of which amount corresponds to an amount required for forming a predetermined coat thickness is continuously and constantly supplied to the surface of the sheet-like substrate, and the coating bar is moved up and down on the basis of increase and decrease in an amount of a holdup of the coating liquid which is formed just near the coating bar, so that the coat is formed.
