PROBLEM TO BE SOLVED: To improve the flattening properties of a machining face by retaining the difference in electric resistance between the recessed part and the projecting part in the surface of the object to be machined. SOLUTION: The electrochemical machining device comprises: a machining electrode 60 capable of freely approaching the object to be machined; a power feeding electrode 62 of feeding power to the object to be machined; a contact member 70 arranged between the object to be machined and the machining electrode, and in which the deformation volume by a contact load to the object to be machined is set to the initial height of the ruggedness in the surface of the object to be machined or lower; a power source 48 of applying voltage between the machining electrode 60 and the power feeding electrode 62; and liquid feeding parts 62a, 62b, 66b, 66c of feeding liquid to at least either the space between the object to be machined and the machining electrode 60 or the power feeding electrode 62.
