    摘要: A composite magnetic material manufactured by mixing a metal magnetic powder with an insulating binder to produce a mixed powder, press-molding the mixed powder to produce a molded product, and heat-treating the molded product in an oxidizing atmosphere at not lower than 80° C. and not higher than 400° C. to form an oxide film on a surface of the molded product. The metal magnetic powder includes Si, Fe, and component A, and the composition thereof satisfies 5.5%≦Si≦9.5%, 10%≦Si+component A≦13.5%, and the remainder is Fe, where % denotes weight %. The component A includes at least one of Ni, Al, Ti, and Mg.

    摘要: An inductance component is disclosed. This inductance component includes base made of insulating material, coil section buried in base, and external electrode terminals electrically coupled to the ends of coil section. Stress buffering section is provided on the exposed interface between base and external electrode terminals, and this stress buffering section can ease the stress produced by the difference in thermal coefficients due to temperature changes. The foregoing structure thus allows improving the reliability of the inductance component with respect to a thermal shock.
