Rod manufacturing method and anode device

Abstract

This method for manufacturing a rod is a method for manufacturing a rod by plating the rod, and includes: a step of arranging the rod in a first tube body formed by arranging a plurality of rod-shaped members in an annular shape; and a step of plating the rod by causing a plating liquid to flow in one direction through a first flow path between the first tube body and the rod.

1 . A method for manufacturing a rod by plating the rod, comprising:
 a step of arranging the rod in a first tube body formed by arranging a plurality of rod-shaped members in an annular shape; and   a step of plating the rod by causing a plating liquid to flow in one direction through a first flow path between the first tube body and the rod,   wherein each of the rod-shaped members is covered with a platinum at least on a surface facing the rod, and has a polygonal column shape.   
     
     
         2 . The method for manufacturing a rod according to  claim 1 ,
 wherein the rod-shaped member has a rectangular column shape having a first surface formed by first side portions and second side portions that are shorter than the first side portions and plated with platinum, and a second surface formed by third side portions that are shorter than the first sides and the second sides, and   wherein the first surface is caused to face the rod, and the plating liquid is caused to flow between the first surface and the rod.   
     
     
         3 . The method for manufacturing a rod according to  claim 1 ,
 wherein a gap is provided between the rod-shaped members adjacent to each other,   wherein a second tube body is disposed on an outer peripheral side of the first tube body, and a second flow path is provided between the first tube body and the second tube body, and   wherein the plating liquid is caused to flow in and out between the first flow path and the second flow path via the gap while the plating liquid is caused to flow in one direction through the first flow path between the first tube body and the rod.   
     
     
         4 . An anode device comprising a plurality of rod-shaped members that are disposed in an annular shape to form a first tube body and form a space through which a plating liquid flows between the first tube body and a rod disposed in the first tube body,
 wherein a positive voltage is applied to the anode device,   wherein each of the rod-shaped members is covered with a platinum at least on a surface facing the rod, and has a polygonal column shape.
