The following treatment was respectively performed with the composite oxides of the Manufacturing Examples 1 to 5. That is, a predetermined amount of a palladium nitrate-dihydrate was dissolved in ion-exchanged water, whereby a palladium nitrate solution was obtained. The palladium nitrate solution and a predetermined amount of composite oxides (KNbO3, NaNbO3, KTaO3, Al2O3 and LiNbO3) powder were put in an eggplant-shaped flask, and while the flask was evacuated by a rotary evaporator, a mixture of the solution and the powder was evaporated and solidified in a hot bath at 60° C. After heating up to 250° C. at a rate of 2.5° C./min in a muffle kiln, the temperature of the mixture was further raised to 750° C. at a rate of 5° C./min, and the mixture was held at 750° C. for 3 hours. As a result, catalyst powders of Manufacturing Example 1 to 5 in which PdO is impregnated and supported on the above-mentioned composite oxides or oxide were obtained.
