PROBLEM TO BE SOLVED : To provide a perovskite type multiple oxide which suppresses reduction of its specific surface area under a high temperature condition. SOLUTION : The perovskite type multiple oxide is represented by the formula : ABxTi1-xOα and a BET specific surface area of the multiple oxide after firing in the atmosphere at 1, 000°C for 3 h is ≥15 m2/g. In the formula, A denotes a rare earth metal; B denotes aluminum or a transition metal; x denotes a numerical value of 0
