PROBLEM TO BE SOLVED: To provide a die coating device capable of easily changing a coating width and preventing a coating liquid from leaking from the deckle inserting part of a die nozzle. SOLUTION: The die coating device is constituted in such a way that an opening 12a is formed as a coating liquid exit by inserting a deckle 3 into the die nozzle 100, and that a reduced pressure chamber 4 for forming a bead is added. A gap between the deckle 3 and slot 12 inner surface at the deckle inserting part is sealed by covering the deckle inserting part with a rectangular wrap sheet 2 in a tension state stuck firmly to the deckle 3 inserting part. In this case, the wrap sheet 2 is expanded and supported by a pair of wrap sheet holders 6, 7 by fixing both the end parts in the longitudinal direction of the wrap sheet 2 to the pair of wrap sheet holders 6, 7 and by properly tensioning the wrap sheet by a tensioner 5.
