Abstract

In order to easily form curved holes and straight holes of desired shapes, an electrochemical machining tool of the present invention comprises a tool body including: an electrode made from an electrically conductive material in a cylindrical shape extending along an axial line and having flexibility, an electrolytic solution flowing through an internal flow channel of the electrode toward a tip side; and an insulating layer coated on an outer circumferential face of the electrode so as to expose the tip of the electrode. A fluid outflow hole is formed in the tool body, passing through the tool body in a radial direction and guiding the electrolytic solution flowing through the flow channel outward in the radial direction, and the electrochemical machining tool further comprises a tube-shaped member selectively opening and closing the fluid outflow hole.
