Pulsed wire discharge (PWD) is one of nano-sized powder production methods and has been applied for development of mass-produced apparatus.  However, methods of collecting produced powders have not been developed yet, and are the major problem of the mass-produced apparatus.  Thus, we developed an electrostatic collector for PWD to examine availability and to measure the powders collection efficiency.  It was found from the results that we succeeded in collecting nano-sized powders using the electrostatic collector.  Anode corona had high powder collection efficiency than cathode corona.  This was attributed to the fact that nano-sized powders produced by PWD were positively charged or corona discharge characteristics were different.
