Claim 7:
8. A device for electrical stimulation, comprising:
a first terminal electrode having a first opening at a center thereof;
a first ground electrode disposed on an opposite side to the first terminal electrode with respect to an object disposed therebetween and having an area smaller than an area of the first terminal electrode;
a second terminal electrode having a second opening at a center thereof;
a second ground electrode disposed on an opposite side to the second terminal electrode with respect to the object disposed therebetween and having an area smaller than an area of the second terminal electrode; and
a power source,
wherein the second ground electrode is disposed at a center of the first opening,
the first ground electrode is disposed at a center of the second opening, and
the power source is configured to apply an electrical stimulus to the object by applying a terminal voltage alternately to a pair of the first terminal electrode and the first ground electrode and a pair of the second terminal electrode and the second ground electrode.
