Abstract
A pulse current from a pulse current supply side is fed to a middle part of an anode holding body to which anodes are connected; both end portions of a cathode holding body, to which cathodes are connected, are connected to a negative pole on the pulse power source side; and inductances of wiring between adjacent anodes and inductances of wiring between adjacent cathodes are set at a ratio of 1:2:3:4 in a direction of spacing from a connection to the pulse power source side. Pulse currents are equally fed to each work and it can be ensured that chromium plating treatment of each work is made equal.
