The present invention provides a core-shell magnetic material having an excellent characteristic in a high frequency band, particularly, in a GHz band. The core-shell magnetic material includes: core-shell magnetic particles including magnetic metal particles and an oxide coating layer, the magnetic metal particle containing magnetic metal selected from the group of Fe, Co, and Ni, nonmagnetic metal selected from the group of Mg, Al, Si, Ca, Zr, Ti, Hf, Zn, Mn, a rare-earth element, Ba, and Sr, and an element selected from carbon and nitrogen, and the oxide coating layer being made of an oxide containing at least one nonmagnetic metal as one of the components of the magnetic metal particle; and oxide particles existing at least a part between the magnetic metal particles and containing nonmagnetic metal selected from the group of Mg, Al, Si, Ca, Zr, Ti, Hf, Zn, Mn, a rare-earth element, Ba, and Sr, and in which nonmagnetic metal/magnetic metal (atomic ratio) in the particles is higher than that in the oxide coating layer.
