PROBLEM TO BE SOLVED: To provide a coating method capable of making a coating film thinner at the lower edge in the down flow direction of a coating liquid in formation of the coating film on a tabular base material by a flow-coat method, the base material being held in the vertical direction.SOLUTION: A production method of a base material with a coating film includes a step for discharging a coating liquid onto at least one principal plane of an object base material from a main nozzle for discharging the coating liquid to form a coating film while moved in the nearly horizontal direction at the upper edge of the principal plane of the base material held vertically or slantly. The production method further includes a step for coating the lower edge of the principal plane with a solvent capable of diluting the main coating liquid while the main coating liquid is kept as a liquid film over the area ranging from the location where the main coating liquid is discharged to the lower edge of the principal plane of the base material.SELECTED DRAWING: Figure 1

    【課題】板状の基材を上下方向に保持したフローコート法による基材への塗布膜の形成で、塗布液の流下方向の縁となる下辺側で、塗布膜の膜厚を薄くすることが可能な塗布方法を提供することを課題とする。【解決手段】本発明の塗布膜付基材の製法は、塗布対象の基材を傾けるか、垂直にした状態で基材を保持し、前記基材の少なくとも一方の主面上の上辺側で、塗布膜を形成するための塗布液を吐出する主ノズルを略水平方向に相対移動させながら、前記主ノズルから前記塗布液を前記基材の主面上に吐出する工程を備えるものであり、前記主塗布液が、前記主塗布液の吐出位置から前記基材の主面上の下辺側に渡って、液膜として保持された状態で、主面上の下辺側に、前記主塗布液に対して希釈性のある溶剤を塗布する工程を備えること。【選択図】図1
