PROBLEM TO BE SOLVED: To provide a die coater capable of improving a film thickness distribution in the width direction of a coated film and suppressing the length of the coated film, and a manufacturing method of a coated film.SOLUTION: A die coater comprises: a die block body including a manifold and a slit communicating with the manifold for discharging a coating liquid; and a spacer arranged at each of the two widthwise end parts of the slit for defining the width of a passage of the coating liquid. The area of the notched region of the spacer is larger than that of a virtual triangle. 【課題】塗膜の幅方向における膜厚分布の改善と、塗膜の端部の長さを抑制できるダイコーター、及び塗布フィルムの製造方法を提供する。【解決手段】マニホールドと前記マニホールドに連通し塗布液を吐出するスリットとを有するダイブロック本体と、前記スリットの幅方向の両端部にそれぞれに配置され、前記塗布液の流路の幅を画定するスペーサーとを備えるダイコーターであって、スペーサーの切欠領域の面積が仮想三角形の面積より大きい。【選択図】図５
