Abstract
In a coater for applying a liquid onto a surface of a moving object, the coater includes a front edge surface, a back edge surface and a slit, wherein the back edge surface has an entrance edge from which the coating liquid is introduced into a gap between the back edge surface and the surface of the object and an exit edge from which the extruded coating liquid leaves the gap with the movement of the object. The back edge surface further is arranged in relation to the object so as to satisfy following two formulas; 1.0 mm.ltoreq.L.ltoreq.30 mm and 1.8.ltoreq.h/h.sub.0 .ltoreq.3 where L is a length of a contour of the back edge surface projected on the surface of the object between the entrance edge and the exit edge; h is a gap distance at the entrance edge; and h is a gap distance at the exit edge.
