PROBLEM TO BE SOLVED: To provide a titanium-containing perovskite-type composite oxide having a small particle diameter, a narrow particle size distribution, good dispersibility, high crystallinity and excellent electric properties, and to provide a production process thereof. SOLUTION: The titanium-containing perovskite-type composite oxide is represented by the compositional formula: A(Ti<SB>x</SB>B<SB>(1-x)</SB>)<SB>y</SB>O<SB>3</SB>(wherein, 0<x<1; 0.98≤y≤1.02; A is at least one element selected from Ca, Sr, Ba, Pb and Mg; and B is at least one element selected from Hf and Zr).
