PURPOSE:To provide a magnetic composition whose permeability is small in frequency-dependent properties in a high-frequency band, large in permeability to a certain extent, and excellent in thermal shock resistance. CONSTITUTION:A magnetic composition is composed of 4 to 48% polyarylensulfide by mass, 50 to 94% Ni-Zn-Cu ferrite powder represented by a formula, (NiO)a(ZnO)b(CuO)c(Fe2O3)d, by mass, and 2 to 30% glass fiber by mass, wherein a, b, and c are so set as to satisfy formulas, a+b+c+d=1, 0.34<=a<=0.43, 0.08<=b<=0.20, 0<=c<=0.06, and 0.47<=d<=0.50. |
