Abstract
An electric discharge is generated between an electric discharge surface treatment electrode and a wire electrode, and an electric discharge surface treatment material is stuck on the surface of the wire electrode by the energy of the electric discharge. An electric discharge is then generated between a work piece and the wire electrode on which the electric discharge surface treatment material is stuck, and a surface modified layer is formed on the surface of the work piece by the energy of the electric discharge.
