PROBLEM TO BE SOLVED: To provide an electrochemical machining electrode tool and a manufacturing method for it, attaining very high adhesion of an insulating material and an electrode tool base material, whereby even in a long-time use, electrolyte will not permeate into an interface between the insulating material and the electrode tool base material to maintain high accuracy over a long period of time, and also dispensing with an insulating material filling tool for insulating resin mold to facilitate manufacture. SOLUTION: This electrochemical machining electrode tool includes: a conductive pattern formed by a projecting part 5 to 50μm high, in which the electrode tool base material is exposed; and an insulating thin film formed of deposited polymer resin or deposited resin 5 to 50μm provided on the surface of the electrode tool base material outside of the conductive pattern.
