That is, when the thickness of the sintered body 9 is t, the distance between the electrodes 10 and 11 is
W 1 must be W 1 >2t. In addition, the distance between the electrodes 10 and 12 or the electrodes 11 and 12
W 2 must be such that W 2 >t. When this condition is not satisfied, the current will not flow inside the sintered body 9,
It flows on the surface of the sintered body 9 and easily deteriorates.
