PROBLEM TO BE SOLVED: To provide a resin ferrite core whose initial magnetic permeability is high, and resin ferrite materials to be used for manufacturing the resin ferrite core, and a method for manufacturing the resin ferrite materials. SOLUTION: Soft ferrite particles P constituting resin ferrite materials are constituted of rough powder ferrite particles whose particle diameter is ranging from 700-2000μm and fine powder ferrite particles whose particle diameter is ranging from 50-110μm. A resin layer constituting the resin ferrite materials is formed by spraying resin solution L while circulating the soft ferrite particles P by convection with inert gas in a fluidized-bed device 1.
