A composite ferrite material is provided. The composite ferrite material obtained from a mixture of a magnetic ferrite powder with high crystallinity, prepared by firing at a prescribed temperature, and a glass powder, having a softening temperature lower than said firing temperature, by heat treatment of said mixture at a temperature which is higher than, or equal to said softening temperature of said glass powder and lower than, or equal to said firing temperature, to effect the binding of said magnetic ferrite powder by said glass material. The composite ferrite material has excellent magnetic characteristics and can be obtained in a form of the desired dimensions with high accuracy.
