PURPOSE:To prevent vibration of an electrode part of a blade part machining electrode for an integral type disk. CONSTITUTION:A blade back part forming electrode part 21 of providing protrusive parts 26, 27 is provided in one end or both ends of an electrode part 25 having a blade back part forming curved surface 22 of almost similar shape to a blade to be formed in one surface, and a blade belly part forming electrode part 23 of providing protrusive parts 29, 30 is provided in one end or both ends of an electrode part 28 having a blade belly part forming curved surface 24 of almost similar shape to a belly surface of a blade to be formed in one surface. In the case of oppositely arranging the blade back part forming electrode part 21 and the blade belly part forming electrode part 23, an electrode section is constituted such that a flow path 31, surrounded by both the electrode parts 21, 23 and the protrusive parts 26, 27, 29, 30, is formed and further an opposed space between both the electrode parts 21, 23 can be changed, and without increasing thicknesses of both the electrode parts 21, 23, vibration of the electrode parts 21, 23 is prevented.
