To provide a coating method for reducing ununiformity of coating by separation of a coating liquid and defect by mixing of a foreign matter and forming a coating film of high quality on a substrate even with a simple constitution being excellent in practical use, and a coating apparatus.

By covering a liquid reservoir part 8 stored with a coating liquid 15, moisture absorption and volatilization of the coating liquid are suppressed and ununiformity of coating caused by these is sufficiently reduced. Further, by covering the liquid reservoir part, the foreign matter is prevented from being mixed into the coating liquid.
