PROBLEM TO BE SOLVED: To provide a method of forming coated film for taking an allowance range of a gap between a die and a base material large in coated film formation by slot coating, and to provide a method of manufacturing coated film laminate. SOLUTION: The method of forming coated film includes: a step of arranging a sheet-like base material on a roller having a diameter D (mm); a step of causing the roller to rotate; and a step of supplying coating liquid from the die to the surface of the base material rotating while following up the roller, wherein the die has an upstream side lip surface as a surface capable of retaining the coating liquid between the die and the base material and a downstream side lip surface which is arranged more on the downstream side in the rotation direction from the upstream side lip surface and is a surface capable of retaining the coating liquid between the die and the base material, an interval that ejects the coating liquid is formed between the upstream side lip surface and the downstream side lip surface and the length of the upstream side lip surface in the roller rotation direction is 2.0-0.02D (mm).
