Abstract
In a case to coat a web by using coating heads which have plural slits, the coating method coats the web by adjusting a running speed, an average high shear viscosity, and a surface tension of the coating liquid of the top layer so that the capillary number Ca, which is calculated by an equation Ca═U&mgr;/&sgr;, satisfies an inequality 0.1<Ca<4, where U (m/s) is a running speed of the web, &mgr; (Pa·s) is an average high shear viscosity of the coating liquids, and &sgr; (N/m) is a surface tension of the coating liquid for the top layer.
