A ceramic member containing an insulating member is disclosed. The ceramic member comprises a ceramic body and an insulating layer on the ceramic body. The ceramic body contains aluminum oxide crystals and aluminum titanate crystals. The insulating layer contains silicon oxide as a main component. The ceramic body includes a first region that includes a first surface portion covered by the insulating layer, and a second region outside the first region, and having a surface resistivity of 1×10to 1×10Ω/□. A surface resistivity of the first region is higher than the surface resistivity of the second region. 1. An insulating-member-containing ceramic member comprising:a ceramic body that contains an aluminum oxide crystal phase and an aluminum titanate crystal phase; andan insulating layer on a surface of the ceramic body, and containing silicon oxide as a main component, a first region that includes a first surface portion covered by the insulating layer; and', {'sup': 6', '9, 'a second region outside the first region, and having a surface resistivity of 1×10to 1×10Ω/□, and'}], 'wherein the ceramic body compriseswherein a surface resistivity of the first region is higher than the surface resistivity of the second region.2. The insulating-member-containing ceramic member according to claim 1 , wherein the ceramic body has a cylindrical shape comprising a first end surface claim 1 , a second end surface opposing to the first end surface claim 1 , and a penetrating hole penetrating between the first end surface and the second end surface;the first region lies in a central region of an outer peripheral surface of the ceramic body and between the first end surface and the second end surface; andthe second region is continuous through an inner peripheral surface of the penetrating hole between the first end surface and the second end surface of the ceramic body.3. The insulating-member-containing ceramic member according to claim 1 , wherein the ceramic body contains an ...
