Abstract

A coating apparatus includes: a conveyor for conveying an object to be coated; and a coater for coating a coating liquid by jetting the coating liquid from a slit in a film shape and by causing the coating liquid to collide with the object to be coated. The coater is not in contact with the object to be coated, and a clearance of a slit exit d (m) of the coater satisfies a relation of 0<d.ltoreq.5.times.10.sup.-5 (m). The clearance of the slit exit of the coater is smaller than a clearance of a slit inlet through which the coating liquid is injected, the slit has, on a side of the slit exit, slit side surfaces which face each other to be in parallel.
