To provide a coating apparatus which can stably and uniformly coat while preventing the occurrence of turbulent flow of a coating liquid.

The tip face of a first doctor edge tip 17 attached to a first doctor edge is made so that its curved face 23 present along the width direction of a flexible band-like support 19 is made bulgy toward the flexible band-like support 19. The tip face of a second doctor edge tip 18 attached to a second doctor edge is made so that a bulgy streak 24 present along the width direction of the flexible band-like support 19 is made bulgy toward the flexible band-like support 19. The bulgy streak 24 is formed so that arcs different in radius of curvature at the upstream and downstream sides are smoothly connected so as to have the same tangential line, forming a composite arc face having a wing-line-shaped cross section.
