<P>PROBLEM TO BE SOLVED: To provide a multi-wire electrical discharge machine that can suppress a current flowing from an adjacent cutting wire into a discharge point generated in a certain cutting wire. Ž<P>SOLUTION: The multi-wire electrical discharge machine includes: a plurality of guide rollers 3 disposed at certain intervals; an electrode wire 1 forming a plurality of cutting wires 2 separated from one another between a pair of guide rollers 3, the electrode wire wound around each of the plurality of the guide rollers 3; and a plurality of power feeding elements feeding power from the power source to the cutting wires 2, the power feeding elements contacting with a plurality of the cutting wires 2 individually, wherein electric resistance from each of the power feeding elements to each of the cutting wires contacting with the power feeding elements individually is smaller than the electric resistance up to the adjacent cutting wires by not lower than 50 Ω.
