Zusammenfassung:	To provide techniques for increasing the catalytic performance in a low temperature range and decreasing the degradation in a high temperature range in a sintered ceramic.SOLUTION: The sintered ceramic comprises: a perovskite-type oxide represented by the general formula ABO3 and containing at least Mn in the B sites; and (Ni,Mn)3O4; where the content of Ni atoms based on the total amount of metal atoms contained in the sintered ceramic is 25 mol% or less.SELECTED DRAWING: Figure 2 【課題】セラミック焼結体において、低温域における触媒性能を大きくし、高温域における劣化を抑制する技術を提供する。【解決手段】セラミック焼結体は、一般式ＡＢＯ3で表され、Ｂサイトには少なくともＭｎを含むペロブスカイト型酸化物と、（Ｎｉ，Ｍｎ）3Ｏ4と、を含み、セラミック焼結体に含まれる金属原子の全体量に対するＮｉ原子の含有量の割合は、２５ｍｏｌ％以下である。【選択図】図２
