The high energy generated from electric pulsed power has various applications. We investigated the underwater shock wave generated by the metal wire explosion and the electric discharge of electrode using high voltage impulsive current. This investigation was performed using optical observation, pressure measurement and current measurement. In the case of metal wire explosion, the velocity, pressure and the current value of underwater shock wave obtained from the experimental data is proportional to the electric resistance rate. In the other case, the discharge from the electrode, the velocity of the underwater shock wave generated by the discharge of electrode with metal wire explosion is faster than the underwater shock wave generated by the discharge of the electrode without metal wire.
