The curtain coating member creates a curtain-like film of coating liquid and makes the curtain-like film flow down. The conveyance unit conveys a base material to which the curtain-like film is to be applied. The separation member includes a receiving portion inclined downward from inside to outside in a width direction of the curtain-like film, and separates an end portion of the curtain-like film having flowed down by receiving the end portion with the receiving portion above the base material. The base material supporting member is disposed inside in the width direction of the curtain-like film than the receiving portion of the separation member, and supports the base material on an upper side flat portion while the base material is being conveyed.
