Abstract
An electromagnetic wave absorber is formed of an Mn—Zn ferrite including: a spinel primary phase which contains 40.0 to 49.9 mol % FeO, 4.0 to 26.5 mol % ZnO, 0.1 to 4.0 mol % TiOand/or SnO, and the remainder consisting of MnO; and a secondary phase which contains CaO as a base component. In the ferrite, the mass of the spinel primary phase accounts for 50.0 to 99.0% of the aggregate mass of the spinel primary phase and the secondary phase.
