A method of producing a coating rod (12) capable of eliminating a scratch and coating irregularities on a web is provided. The method includes the steps of: preparing a rod material (20); arranging paired rolling dies (120,130) each having a plurality of convex shapes formed on an outer perimeter surface, having a chamfer part (120a,130a), a parallel part (120b,130b), and a relief part (120c,130c) from an approaching side toward an exiting side of the rod material, and having a relief angle formed by a surface forming the relief part and a surface of the parallel part of 0.01° to 0.45°, so that the parallel parts face each other; inserting the rod material from a chamfer part side in a space interposed between the paired rolling dies; and forwarding the rod material to a relief part side by the paired rolling dies pressuring the rod material therebetween while rotating and performing a rolling process on a surface of the rod material. |
