摘要： A method for manufacturing a coating rod, comprising the steps of preparing a rod material, disposing a pair of form rolling dies having a plurality of helical convex threads, so that the closure angle of a main axis of each of the form rolling dies in the horizontal direction of the main axis is substantially 0.25° or larger but not larger than 0.35° with respect to an axial direction of the rod material, and form-rolling the rod material by feeding the rod material along the axial direction thereof and rotating the pair of form rolling dies around the main axes thereof, while clamping the rod material with the pair of form rolling dies.
