PROBLEM TO BE SOLVED: To prevent the occurrence of a defect of insufficient bonding in a building-up layer 39 even in the case where the length of a part 3 to be treated of a work 1 is larger than the width of an electrode 35. SOLUTION: In this surface treatment method, while the electrode 35 is relatively moved along the part 3 to be treated of the work 1, a pulse-like discharge is generated between the part 3 to be treated of the work 1 and the electrode 35, thereby depositing material of the like of the electrode 35 on the part 3 to be treated of the work 1 by the discharge energy to continuously form the building-up layer 39 along the part 3 to be treated of the work 1. The relative moving speed of the electrode 35 is a very low speed so that discharge is continued between the edge side 41a of the electrode recessed part 41 and the bottom side 43a of the building-up projecting part 43.
