description PROBLEM TO BE SOLVED: To provide deformed magnetic fine particles which are produced as starting particles from composite fine particles formed by bonding >=2 different kinds of particles. SOLUTION: The composite fine particles composed of a prismatic hematite particles and a plurality of planar goethite particles which are hetero-bonded to the prismatic hematite particles, are used as starting particles. The planar goethite particles radially grow in a C crystalline axis direction of the planar goethite particle in a radial form in mutually opposite directions with C crystalline axis of the prismatic hematite particles as a symmetry axis center.
