Abstract
Ni—Cu—Zn based oxide magnetic materials, in that not only the internal conductor is stabilized at very low firing temperatures, but also the characteristics in the high frequency zones of 100 MHz or higher are excellent. The oxide magnetic materials comprises, Fe2O3: 35.0 to 51.0 mol %, CuO: 1.0 to 35 mol %, NiO: 38.0 to 64.0 mol %, ZnO: 0 to 10.0 mol % (including 0%) and Ca: 0.3 wt % or lower (not including 0%), and, optionally, CoO: 0.7 wt % or lower.
