HIGH-WITHSTANDING-VOLTAGE ALUMINA SINTERED COMPACT AND HIGH-WITHSTANDING-VOLTAGE MEMBER
[Object] To provide a high-withstanding-voltage alumina sintered compact in which creepage breakdown is unlikely to occur even if a voltage is applied, and a high-withstanding-voltage member including the high-withstanding-voltage alumina sintered compact on which electrodes are provided. [Solution] The high-withstanding-voltage member includes an alumina sintered compact containing alumina as a main crystal. Since the alumina sintered compact exhibits a peak intensity of 5000 or less at a wavelength of about 330 nm when measured by a cathode luminescence method, the sintered compact allows application of high voltage before reaching creepage breakdown and, accordingly, reduces the occurrence of instantaneous voltage drop. Consequently, data missing resulting from instantaneous voltage drop can be reduced.
