1. A coating apparatus comprising: a forward bar rotatable about an axis in a direction following a traveling direction of a continuously traveling band-shaped web while the forward bar touches the web; a liquid feed passage for feeding a portion of coating liquid to an area on an upstream side of the forward bar with respect to the traveling direction of the web when coating the web with the coating liquid; a metering device arranged on a downstream side of the forward bar with respect to the traveling direction of the web, for metering the coating liquid applied to the web by the forward bar, to a predetermined coating thickness; a downstream liquid feed passage for feeding an another potion of the coating liquid to an area of the web between the forward bar and the metering device; and a pump that provides the other potion of the coating liquid to the downstream liquid feed passage, wherein the metering device is a backward bar arranged parallel with the forward bar rotatable in an opposite direction to the traveling direction of the web while the backward bar touches the web.
