Claim:
A coating device for coating a coating liquid on a surface of a belt body which is conveyed in a certain direction, the coating device comprising: a first side bar which extends along a transverse direction of a conveyance plane, which conveyance plane includes a conveyance path of the belt body; a second side bar at a downstream side relative to the first side bar, which extends in parallel with the first side bar; a first side coating liquid supply channel, which supplies the coating liquid at an upstream side at the first side bar; an inter-bar liquid-pooling section located between the first side bar and the second side bar, which accumulates the coating liquid at a time of coating of the coating liquid; and a connecting channel which channels the coating liquid from the inter-bar liquid-pooling section to the first side coating liquid supply channel so as to lower the coating liquid in the inter-bar liquid-pooling section, wherein an air-liquid boundary surface is formed between the coating liquid and air, between the belt body and the inter-bar liquid-pooling section.
