COATING METHOD AND COATING APPARATUS

A coating method of repeatedly forming a lower surface coated portion obtained by forming a coating film on a lower surface of a base material and a lower surface uncoated portion obtained by exposing the lower surface of the base material between a terminal end of a lower surface coated portion and a starting end of the lower surface coated portion, by switching on/off in supply of a coating liquid to a slit die facing the lower surface of the base material through a discharge port while the base material is transferred, in which a distance between the lower surface of the base material and the discharge port of the slit die is temporarily expanded beyond a distance so far by a base material height changing device during a specific period from termination of the supply of the coating liquid to the slit die to restarting of the supply is provided. Accordingly, a gap between the base material and the slit die can be maintained contrary to an operation in which the base material is drawn into the coating liquid at a terminal end of the lower surface coated portion. Further, the shape of the coating film at the terminal end of the lower surface coated portion is improved and linearity of the terminal end of the lower surface coated portion is improved. 1.
