PROBLEM TO BE SOLVED: To provide a small size ceramic green material formed in a complicated shape, a ceramic sintered material, a manufacturing method for obtaining ferrite core, a ceramic green material manufactured with such manufacturing method, a ceramic sintered material, a ferrite core, and a coil component. SOLUTION: First, ferrite powder, thermosetting resin and surface active agent are prepared and these are heated and kneaded (kneading process: S101). Next, a composition obtained by heating and kneading is granulated to particles to obtain pellets (granulating process: S103). The composition pellet is injected to a metal die to obtain a molded material (injected molding process: S105). A binder is removed (so-called defatted) from the injected molding material (defatting process: S107). Next, defatted molded material is sintered (sintering process: S109). Consequently, a ferrite core can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
