To provide a magnetic body ceramic for high frequency in which the increase of frequency, the lowering of loss and the stabilization of temperature are attained and a high frequency circuit component.

The magnetic body ceramic for high frequency consists essentially of garnet-type ferrite expressed by a general formula, (Yz-a-bCaaGdb)(Fe8-z-c-dIncVd)O12 and satisfies 3.00<z≤3.09, 2.00<a/d≤2.40, 0≤b≤2.00, 0<c<1.00 and 0<d≤1.50. The high frequency circuit component is designed using the magnetic body ceramic for high frequency.
