PROCESS FOR PRODUCING MAGNETIC POWDER, PROCESS FOR PRODUCING MAGNETIC SHEET, AND PROCESS FOR PRODUCING ANTENNA MODULE

摘要

[PROBLEMS] Provided are: a process for producing a magnetic powder which is composed of magnetic particles having a reduced size to attain a thickness reduction and has a low loss and which does not reduce magnetic permeability or is capable of improving magnetic permeability; a process for producing a magnetic sheet; and a process for producing an antenna module. [MEANS FOR SOLVING PROBLEMS] At least two magnetic oxide materials are mixed together (step 102), and the mixture is calcined (step 103) and pulverized (step 104). The pulverized magnetic materials are dispersed typically in an organic solvent to obtain a paste. The resultant magnetic material is degassed and then applied to a film (step 105) to thereby form a sheet-form magnetic material (51). The sheet-form magnetic material (51) is cut into a given size so as to be divided into particles. Thus, magnetic particles (52) are formed (step 106).
