To suppress deterioration in coating quality.SOLUTION: A coating applicator 200 includes a process liquid storage container 202 for storing process liquid 201, a scoop-up roller 205 which is stored in the process liquid storage container 202 and scoops up the process liquid 201, a coating roller 206 which transfers the process liquid 201 by the scoop-up roller 205 and coats the process liquid 201 to a sheet material P, and a defoaming blade 210 as a contact member contacting a peripheral surface of the coating roller 206, wherein the defoaming blade 210 contacts the peripheral surface of the coating roller 206 in a rotation direction of the coating roller 206, on the downstream side of a coating position a where the process liquid 201 is coated to the sheet material P by the coating roller 206, and on the upstream side of a supply position b to which the process liquid 201 is supplied from the scoop-up roller 205.SELECTED DRAWING: Figure 5 【課題】塗布品質の低下を抑制する。【解決手段】塗布装置２００は、処理液２０１を収容する処理液収容容器２０２と、処理液収容容器２０２に収容され処理液２０１を汲み上げる汲み上げローラ２０５と、汲み上げローラ２０５で処理液２０１が移送され、シート材Ｐに処理液２０１を塗布する塗布ローラ２０６と、塗布ローラ２０６の周面に当接する当接部材としての消泡ブレード２１０とを備え、消泡ブレード２１０は、塗布ローラ２０６の回転方向において、塗布ローラ２０６が処理液２０１をシート材Ｐに塗布する塗布位置ａより下流側で、汲み上げローラ２０５から処理液２０１が供給される供給位置ｂより上流側で塗布ローラ２０６の周面に当接する。【選択図】図５
