PURPOSE: A magnetic composition is provided to achieve improved quality coefficient and dielectric constant and stabilized temperature coefficient of resonance frequency in a microwave band. CONSTITUTION: A magnetic composition contains, as a main component, the material expressed as a chemical formula of £Ca1-x(Li1/2Nd1/2)x|TiO3 based 0<x<1.0(wherein x is weight%). The magnetic composition has a dielectric constant(K) of 131.8 to 180.6, a quality coefficient(Qf) of 777 to 6509GHz, and a temperature coefficient of resonance frequency of 21.9 to 800ppm/Deg.C in case where the mole fraction of x changes. The magnetic composition has a dielectric constant of 47.3 to 58.13, a quality coefficient of 12262 to 13032GHz, and a temperature coefficient of resonance frequency of 14.34 to 28.17ppm/Deg.C in case the mole fraction of x is fixed as 0.4, the magnetic composition contains, as a main component, £Ca1-x(Li1/2,Nd1/2)x|1-yZnyTiO3 based 0<y<1.0(wherein y is weight%), and the mole fraction of y changes.
