It is an object to provide a ferrite material which has a higher saturation magnetic flux density and low core loss, both at 100° C. The ferrite material is composed of a sintered body containing Fe, Mn and Zn as main constituents at x, y and z % by mol in terms of Fe<SUB>2</SUB>O<SUB>3</SUB>, MnO and ZnO, respectively, and containing Li as an additive at v % by weight in terms of Li<SUB>2</SUB>CO<SUB>3 </SUB>based on the main constituents, wherein x=55.7 to 60, z=3 to 8.5, y=100-x-z, v=0.3 to 0.8, and x1<=x<=x2 (x1=52.9-0.1z+8.5v and x2=54.4-0.1z+8.5v).
