摘要：
A composite sintered magnetic material comprises a kind of metal powder at least one selected from the group consisting of Fe, Fe—Si type, Fe—Ni type, Fe—Ni—Mo type, and Fe—Si—Al type, and a ferrite layer formed from a kind of ferrite powder at least one selected from the group consisting of Ni—Zn type, Mn—Zn type, and Mg—Zn type, wherein a diffusion layer is formed by sintering between both of these to integrates the both.
