<P>PROBLEM TO BE SOLVED: To provide a radio wave absorber which is reduced in manufacturing cost while keeping a required characteristic level high, and improved in chipping resistance. <P>SOLUTION: The radio wave absorber made of an MnZn-based ferrite sintered body has a principal component consisting of 45.0 to 49.0% by mol of ion oxide in terms of Fe<SB>2</SB>O<SB>3</SB>, 19.0 to 23.0% by mol of zinc oxide in terms of ZnO, and 28.0 to 36.0% of manganese oxide in terms of MnO, and contains predetermined amounts of cobalt oxide, silicon oxide, vanadium oxide, calcium oxide, and niobium oxide respectively as a sub-component for 100 parts by weight of the main component. <P>COPYRIGHT: (C)2009,JPO&INPIT |
