Being the electrode for the plasma in the liquid which generates the plasma the electrode for the plasma in the liquid, the plasma

摘要

A liquid plasma electrode for generating a plasma in the liquid L, the conductive member 11 having a discharge end surface 111 in contact with the liquid L, liquid plasma electrode 1 according to the present invention, except for at least the discharge end face 111 I have, and the insulating member 16 covering the outer periphery of the conductive member 11. Preferably, substantially parallel insulating member 16 d, the discharge end surface 111 a length of a short side minor, if the substantially rectangular cross-section of the guide Den-tan portion 110 of the conductive member 11 having a discharge end face 111 is in the substantially circular and in which when an x, the distance to the surface including the discharge end surface 111 from the reference surface 161 and reference surface 161 end face 161, is satisfied -2d ≦ x ≦ 2d. With this configuration, liquid plasma electrode that may be including a conductive liquid such as water or alcohol, to generate plasma easily in a liquid in a wide range, and further, liquid plasma generating device having the electrode, the liquid plasma generation method using an electrode is provided.
