A method for producing ferrite hollow particles having a hollow structure
formed by mutual sintering of ferrite powder, including: a) a step of
mixing a resin powder and a ferrite powder of a particle size smaller
than that of the resin powder under compaction thereby forming ferrite
powder-coated particles in which ferrite powder coats, in a partially
embedded state, surface of the resin powder; and b) a step of heat
treating the obtained ferrite powder-coated particles thereby removing
the resin powder and mutually sintering the ferrite powder.
