る。EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a common electrode 22 is formed on one side of an insulating plate 21. A large number of small holes 3 of about 80 μm are formed in this common electrode 22. On the other side of the insulating plate 21, A fine electrode 24 is formed.The fine electrode 24 has a hole 26 formed in its ring-shaped portion 26 with a diameter approximately 0.1ffff larger than the diameter of a drill 27, which is a tool.
6 corresponds to the small hole 23 of the common electrode 22 so that its axis substantially coincides with the small hole 23 of the common electrode 22. In this state, align the axis of the drill 27 with the axis of the small hole 23 of the common electrode 22 so as to leave a gap in () in Fig. 1, and move the drill 27 forward from the small hole 23 side (Fig. 1(C)). As shown in the figure, holes 28 (φ0.1H to φo,
3ff) and are penetrated by this hole 28 and hole 26.
