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 and the ionic flow were measured simultaneously to examine the relationship of the outbreak mechanism of wire oscillation and the fluid force due to the ionic flow. As the result, the characteristic of the ionic flow has four time zone in the formation process and the string oscillation starts to grow after the ionic flow reached the fourth zone of the four time zone.
