PROBLEM TO BE SOLVED: To provide a power supply connection structure capable of effectively suppressing heat generation at a connection part between an electrode and feed wiring, and to provide an electrolytic processing device in which the feed wiring is connected to the electrode with the power supply connection structure. SOLUTION: The power supply connection structure of the electrode includes a rod-shaped electrode 10 having at least one end part of which the diameter is reduced toward the end face, a power feeding member 2 which is formed of a conductor, connected to the feed wiring 4, includes an inner lumen 3 being a recessed part formed so that sidewall faces are reduced toward the bottom face, and has a diameter-reduced part 10A of the rod-shaped electrode 10 inserted into the inner lumen 3, and coil springs 13 by which the feeding member 2 attached to the diameter-reduced part 10A of the rod-shaped electrode 10 is pressed toward the diameter-reduced part 10A. The power feeding member 2 in a state of being attached to the diameter-reduced part 10A of the rod-shaped electrode 10 is formed so that the sidewall faces 3A of the inner lumen 3 are tightly adhered to the outer peripheral face of the diameter-reduced part 10A, and a gap is formed between the bottom face 3B of the inner lumen 3 and the end face 10B of the diameter-reduced part 10A.
