Abstract
A ceramic memberaccording to the present invention includes a ceramic base, which contains a solid solution Mg(Al)O(N) in which Al and N components are dissolved in magnesium oxide as the main phase, and an electrodedisposed on a portion of the ceramic baseand containing at least one of nitrides, carbides, carbonitrides, and metals as an electrode component. The ceramic basemay have an XRD peak of a (111), (200), or (220) plane of Mg(Al)O(N) measured using a CuKα ray at 2θ=36.9 to 39, 42.9 to 44.8, or 62.3 to 65.2 degrees, respectively, between a magnesium oxide cubic crystal peak and an aluminum nitride cubic crystal peak.
