A coating device includes: a rotatable coating bar that is arranged inside a container having a coating fluid inlet and an upper opening; a plurality of pairs of rotatable supports that are arranged intermittently along the longitudinal direction of the coating bar, and that support the coating bar from below; and a weir that is located close to the outer periphery of at least the support. The positional relationship between the support and the weir is determined such that, if a line that connects the shaft center of the support and a point which is the end edge of the weir and which is closest to the support is defined as a straight line and if a point where the straight line intersects with the outer periphery of the support is defined as an intersection point, a straight line that is perpendicular to the straight line and that passes through the midpoint of a line segment does not intersect with the coating bar.
