PROBLEM TO BE SOLVED: To provide an electrolytic processing tool which can enlarge a variable range of a curvature radius of a hole to be processed more than before while being prevented in the occurrence of a shortcircuit.SOLUTION: An electrolytic processing tool has: a cylindrical electrode having conductivity and flexibility, and also having at least one outlet in a radial direction at a tip side which defines a flow passage of an electrolyte therein, is opened at an external peripheral face, and makes the flow passage and the surroundings communicate with each other; an electric insulation layer which covers at least a part of the external peripheral face of the electrode; and a throttle part having at least one outlet in an axial line direction at a tip side rather than the outlet of the electrode in the radial direction which reduces an area of the flow passage compared with a base end side rather than the outlet in the radial direction, and is opened in the axial line direction of the electrode.SELECTED DRAWING: Figure 2 |
