PROBLEM TO BE SOLVED: To provide a coating apparatus capable of applying a highly concentrated highly viscous dispersion widely at a high speed. SOLUTION: In the coating apparatus using a die coater, which has a slot and a pocket formed between two bars by superposing two bars one upon another, to extrude the highly viscous dispersion to a strip-like support supported by a backup roll to be fed continuously from the outlet of the slot to coat the strip-like support, the leading end of the upstream bar among two bars constituting the outlet of the slot of the die coater is longer than that of the downstream bar by 0.5-5 mm and a liquid sump is formed between the leading end of the upstream bar and the leading end of the downstream bar to coat the strip-like support.
