The present invention provides a magnetic material having high bending strength and a small variation rate of relative permeability in a high frequency band, and an electronic component using the magnetic material. A glass - ceramic - a ferrite composition, glass 0.5 wt% or more of R 2 O, based on the total weight of the glass, 5.0 wt% or less of Al 2 O 3, 10.0 % By weight or more of B 2 O 3 and 85.0% by weight or less of SiO 2 , and the weight ratio of Ni-Zn-Cu ferrite to the total weight of the glass-ceramic-ferrite composition is 58% by weight or more and 64% by weight The ceramic filler contains quartz and optionally forsterite, and the weight ratio of quartz is 4% to 13% by weight with respect to the total weight of the composition, and the weight ratio of forsterite is 6% by weight or less The composition has a peak corresponding to the magnetite phase (511) plane in the X-ray diffraction pattern, and the half width of the peak is 0.38 ° or more and 0.56 ° or less Composition.
