A magnetic material includes main components having Fe2O3 of 46.0 to 51.0 mol %, CuO of 0.5 to 15.0 mol % and the rest being NiO. With respect to the main components of 100 wt parts, additives are added. The additives are bismuth oxide of 4.0 to 10.0 wt part in terms of Bi2O3, magnesium oxide of 1.0 to 5.0 wt part in terms of MgO, silicon oxide of 2.0 to 8.0 wt part in terms of SiO2, and cobalt oxide of 0.2 to 0.5 wt part in terms of CoO. Further, an inductor has a core including the above magnetic material, and is composed by molding a resin.
