To provide a coating method for obtaining a coating film of high accuracy with high reproducibility by measuring a coating gap with high accuracy without generating irregularity caused by a method utilizing the perception of a worker by the direct measurement of the coating gap by setting measuring standards on the basis of the surface of a substrate or the outer peripheral surface of a backup roll in a die type coating method for the substrate and directly applying the probe provided to the leading end of a distance measuring means to the leading end of a die nozzle to measure the coating gap, and a coating apparatus using the same.

In the die type coating method for supporting the back surface of the substrate by the backup roll, coating is performed by setting the coating gap between the leading end on the downstream side of a die nozzle lip and the substrate supported by the backup roll on the basis of the surface of the substrate supported by the backup roll opposed to the leading end of the die nozzle lip or the outer peripheral surface of the backup roll opposed to the leading end of the die nozzle lip.
