PROBLEM TO BE SOLVED: To provide a mechanism which lowers a contact pressure between an electric power supply element, which contacts wire groups arranged side by side in a lump, and said wire groups.SOLUTION: A multi-wire electrical discharge machining apparatus for slicing a work-piece by electrical discharge between wire groups arranged side by side and the work-piece, in which an electric power supply unit, onto which an electric power supply element, which contacts the wire groups in a lump and supplies a voltage to the wire groups, is mounted, includes: an installation part onto which the electric power supply element contacting the wire groups in a lump is installed; and an adjustment part which adjusts inclination of the installation part in a direction crossing a travel direction of the wire groups. |
