PROBLEM TO BE SOLVED: To provide a low-loss oxide magnetic material which enables electronic parts using the same to be reduced in power loss and size and improved in thermal reliability and energy-saving properties. SOLUTION: This low-loss oxide magnetic material contains 48.5 to 49.8 mol.% Fe2 O3 , 20.0 to 35.0 mol.% ZnO, 2.5 to 10.0 mol.% CuO, and the residual mold; NiO as main components, and at least one element selected from 0.1 wt.%; or below SiO2 , 0.1 wt.% or below CaO, 0.1 wt.%; or below Nb2 O5 , 0.1 wt.% or below B2 O3 , 0.5 wt.%; or below ZrO2 , 0.5 wt.% or below HfO2 , and 0.5 wt.% or below PbO (excluding 0 wt.%) as an auxiliary component. |
