PROBLEM TO BE SOLVED: To obtain an electrical discharge processing device capable of realizing an electrical discharge processing without breaking a wire when a fixing hole exists on a processing path of a workpiece. SOLUTION: This device comprises a processing condition storage part storing processing conditions including a control parameter at a workpiece shape variation portion corresponding to a kind of a shape formed on a workpiece and a processing section for executing the control parameter, an shape information acquisition part 15 on a processing path for acquiring the shape variation position and the kind of the shape on the processing path, extracting the processing section corresponding to a combination of the kind of the shape and a nozzle separation volume from the processing conditions of the processing condition storage part 13 per shape variation position on the processing path, and creating processing path information set on the processing path, a processing progression position acquisition part 17, and a processing condition decision part 18 for extracting the processing condition corresponding to the kind of the shape in the processing section from the processing condition storage part 13 and setting it as a new processing condition when the current processing progression position reaches the processing section in the processing path information.
