<p>Provided is a modified perovskite type composite oxide with dielectric characteristics at least equal to, or better than, those prior to modification, with which elution of the A site metal is controlled, and with good cracking traits, without substantial elution of a coating component from the coating components to be modified. The modified perovskite type composite oxide is manufactured by applying a primary coating of at least one type selected from a group consisting of TiO2, Al2O3, ZrO2, and Nd2O3 to grain surfaces of a perovskite type composite oxide. The aforementioned primary coating is formed by hydrolyzing at least one type selected from a group consisting of a hydrolyzable TiO2 precursor, a hydrolyzable Al2O3 precursor, a hydrolyzable ZrO2 precursor, and a hydrolyzable Nd2O3 precursor and then baking at 700-1200°C.</p> |
