The outbreak mechanism of self-excited oscillation of the wire electrode due to corona discharge has not been necessarily given yet. In this paper, the string oscillation placed in the corona discharge field is examined to give some useful information on the outbreak mechanism of the wire oscillation. Some experiments axe made to observe the string oscillation. As a result, the string oscillation is self-excited with the fundamental natural frequency of the string oscillation in the beneath and vicinity of the wire electrode, even though there is no self-excited wire oscillation. It is confirmed that the outbreak mechanism of the string oscillation is excited through the effect of the fluid force, and close relation to that of the wire oscillation.
