Abstract: In a coating method, a precoating layer is applied to one surface of a web W laid between a plurality of web guide rollers GR while a leading end surface of an extrusion-type head portion EX is pressed against the one surface of the web.

Further, coating can be done stably in the rod portion by setting the thickness of the precoating layer for a final coating layer and a virtual coating layer.
