A coating head discharges the coating solution in a discharging direction through a slit to a support and is designed such that a slit has a length M (mm) along the discharging direction and a gap G (mm), and a manifold has a coating width L (mm) orthogonal to the discharging direction, a cross sectional area S (mm.sup.2) and a circumferential length R (mm) of a cross section, wherein the coating head and the supplying means are arranged such that the coating solution is supplied symmetrically i...
