ABSTRACT:
The invention provides an apparatus for coating a solution on a tape-shaped flexible support which is moved so as to run along a top surface of coating head. The coating head is slitted so as to form a front edge surface, a back edge surface in order in the moving direction of the flexible support, and a slit therebetween so that the solution is extruded through the slit of the coating head to the flexible support. In this configuration, at least a part of the back edge surface projects beyond the tangent line at the downstream end of the front edge surface.
