Abstract
An electro plating device includes a pipe inside seal mechanism which occludes an inner channel of a steel pipe, a tubular insoluble electrode which is disposed in a pipe end so as to be opposite to a female screw, a plating solution feed mechanism which includes a plurality of nozzles which extend radially with a pipe axis of the steel pipe as a center, and a pipe end seal mechanism which accommodates the nozzles thereinside and is mounted to the pipe end, when viewed in the pipe axial direction, a tip of each of the nozzles is positioned between the female screw and the insoluble electrode, and each of the nozzles injects the plating solution toward a direction which intersects an extension direction of the nozzle, the direction being a rotational direction of a clockwise direction or a counterclockwise direction in which the pipe axis is the center.
