Abstract: According to an embodiment, a winding apparatus includes a winding core and an air flow controller. The winding core winds a belt-shaped structure comprising a substrate and an edge-coating part that covers an edge of a substrate in a width direction, the edge-coating part being coated with a material liquid on a surface of the substrate. The air flow controller has a nozzle that performs at least either ejection or suction of a gas, and adjusts an air flow in the vicinity of the edge-coating part of the film of the belt-shaped structure, which is wound by a winding core.

Abstract: In general, according to one embodiment, a film coating apparatus includes a discharge section configured to discharge a film formation material; a voltage application section configured to apply a voltage to the film formation material, and to set the film formation material at a high potential relative to a film formation object which is subjected to film formation; a mask disposed at a position overlapping a non-coating portion of the film formation object along a direction from the discharge section toward the non-coating portion; and a potential adjusting module configured to make a potential of the mask equal to a potential of the film formation object.
