Claim Text:
1. A semiconductive ceramic sintered compact comprising: a main phase and first and second phases contained in the main phase observed as a result of observation of any face of the sintered compact, wherein the main phase is a ceramic sintered phase comprising Al the first phase is a grain boundary phase comprising a conductive substance-containing conductive phase and Al the second phase is a grain boundary phase containing a conductive phase having the same composition as the conductive phase in the first phase and having a structure that electrically connects the first phases three-dimensionally to each other, wherein the semiconductive ceramic sintered compact comprises SiO wherein the conductive phase contains Fe (iron) and Ti (titanium), wherein the conductive phase contains crystals having an ilmenite structure, wherein the semiconductive ceramic sintered compact has a value not less than 40 according to a powdery X-ray diffractometry, and the value is obtained by, when a powder of the semiconductive ceramic sintered compact mixed with 1% of a Si (silicon) powder having a purity of 99.9999% or more is analyzed by the powdery X-ray diffractometry, a peak area at 32° is divided by a peak area at 28° and then multiplied by 100.
