27 Claims

1. A surface-treatment method, comprising an operation of conveying a base material in a particular direction and a gas-supplying operation of supplying a surface-treating gas onto the surface of the base material, wherein the gas-supplying operation is performed by using a surface-treatment equipment having an opposing member formed at a position separated from the base material and a rotor with a cylindrical peripheral surface facing the opposing member, the opposing member and the cylindrical peripheral surface being separated by a narrow gap from each other, and by rotating the rotor around an axis almost perpendicular to the base material-conveying direction and allowing the surface-treating gas to be dragged by the cylindrical peripheral surface of the rotor into the narrow gap and further fed from the gap onto the base material surface.
