Extrusion coating apparatus and coating film forming method

Abstract

An extrusion coating apparatus applying the coating solution to the substrate through a bead in a state in which a continuously running belt-like substrate and a lip surface on an upstream side and a downstream side in the substrate running direction are adjacent to each other, including: a manifold to which a coating solution is supplied, a coating solution discharge opening discharging the coating solution onto the lip surface to the substrate through a slit through which the coating solution is passed from the manifold, and a spacer for regulating a coating width is provided in both end portions in a width direction of the slit; the spacer having a bending portion; further the spacer having a distal end portion formed to cover the lip surface on the upstream side; and the bending portion of the spacer being made of a material with a hardness of HRA 70 or more.
