필름(F)의 제조 방법은 바(11)를 사용해서 기재(S)에 도공액을 도포하는 도포 공정과, 기재(S)에 도포된 도공액을 건조시키는 건조 공정을 포함한다. 도공액은 수지성분과, 미립자와, 수지성분 및 미립자를 분산시키는 분산매를 함유한다. 바(11)의 표면 자유 에너지는 도공액의 표면 장력보다 높다. A method for producing a film F comprises a coating step for coating a coating liquid on a substrate S using a bar 11, and a drying step for drying the coating liquid that has been coated on the substrate S. The coating liquid comprises a resin component, fine particles, and a dispersion medium that disperses the resin component and fine particles. The surface free energy of the bar 11 is higher than the surface tension of the coating liquid.
