Abstract: To provide a ceramic powder having low bulkiness and good dispersibility.
In the ceramic powder, the volume ratio of aggregated particles having a particle diameter larger than a reference particle diameter is 35 vol. % or more and the volume ratio when ultrasonic dispersion treatment for 10 minutes at an oscillation frequency of 19.5 kHz and an output power of 10 W is applied is 4 vol. % or less. The reference particle diameter is a particle diameter equivalent to a cumulative 0.1 vol. % diameter from the large diameter side when the ceramic powder is subjected to ultrasonic dispersion treatment for 3 minutes at an oscillation frequency of 19.5 kHz and an output power of 150 W.
