摘要：
An oxide of a transition metal element having at least two valences less than 4 is contained in a spherical dielectric ceramic powder. According to a composite dielectric material using the dielectric ceramic powder, the electric resistivity can be made to take such a high value as 1.0×1012 Ω·cm or more while satisfactory dielectric properties are being maintained.
