Beschreibung
Zusammenfassung:	The purpose of the present invention is to produce a porous layer which has excellent film thickness accuracy. This method for producing a porous layer includes: a step of coating a surface of a substrate with a coating liquid that comprises a non-conductive solvent and particles by passing the coating liquid between a coating device and the substrate; and a step of removing the non-conductive solvent from the coating liquid applied on the surface of the substrate. The electric potential difference between the coating device and the substrate when the coating liquid passes between the coating device and the substrate is 1.0x105 V/m or more. 本发明的目的在于，制造膜厚精度优异的多孔层。本发明的多孔层的制造方法包括：通过使包含非导电性的溶剂和粒子的涂布液穿过涂布装置与基材之间而涂布于基材的面的工序；和从涂布于基材的面的所述涂布液中除去所述非导电性的溶剂的工序，所述涂布液穿过涂布装置与基材之间时的、涂布装置与基材的电位差为1.0×105V/m以上。
