(57) [Summary] [Object] To provide a coating method and apparatus for forming a uniform thin-layer coating film without unevenness and unevenness of the coating liquid at high speed. [Structure] Non-pressurized extrusion type coating head According to 10, in the coating method of coating the coating liquid, at the start of coating or at the time of restarting coating, the precoat liquid is first coated on the support 1 while the support 1 is running, and then on the upstream side of the coating head. The support is wrapped around the front edge, the distance between the support and the tip of the back edge is set to 150 μm or less, the coating liquid is discharged from the slit, and then the distance is constantly applied. A coating device 100 configured to enable this method while returning to the above distance for coating. |
