Disclosed is an oxide magnetic material which includes a ferrite having a hexagonal structure as a main phase. The metal elements contained in the oxide magnetic material are expressed as the following formula: Ca1-x-x'LaxSrx'Fe2n-y Coy, and x, x' and y representing atomic ratios and n representing a molar ratio satisfy the following relations: 0.4 <= x <= 0.6, 0.01 <= x' <= 0.3, 0.2 <= y <= 0.45, 5.2 <= n <= 5.8. |
