PROBLEM TO BE SOLVED: To provide a coating method which enables alternate, defectless, and uniform formation of a laminated layer consisting of an upper coating layer and a lower coating layer and a single layer consisting only of the upper coating layer onto a surface of an object to be coated along its moving direction moving relative to a coating apparatus. SOLUTION: The coating apparatus 300 is constituted of a first ejection port 19 from which a first coating liquid 13 is ejected, a second ejection port 20 from which a second coating liquid 15 is ejected, and a third ejection port 21 from which the first coating liquid 13 is ejected, each disposed in line from upstream to downstream as indicated by an allow mark C with the gap between the first ejection port 19 and the object 10 to be coated is narrower than the gaps between the object 10 to be coated and the second ejection port 20 and the third ejection port 21 respectively, whereby the laminated layer consisting of the lower coating layer 29 and the upper coating layer 28 is formed in a step wherein the second coating liquid 15 is ejected from the second ejection port 20 and the first coating liquid 13 is ejected from the third ejection port 21 and the single layer consisting only of the upper coating layer 28 is formed in a step wherein the first coating liquid 13 is ejected only from the first ejection port 19.
