More Information
Summary:An object of the present invention is to provide a coating apparatus and the like that can efficiently form a coating film, in which a width direction thickness variation is sufficiently suppressed. Provided is a coating apparatus including a die that applies a coating liquid on a subject to be coated which is relatively moving, wherein the die includes a manifold that has a uniform cross section in shape and size throughout its width when viewed from the width direction, and an end edge of the manifold on a slot side is formed to draw a quadratic curve determined by a specific formula.
