Abstract

A manufacturing method of a coil component including the steps of: assembling and forming a coil assembly body in which a coil is attached to a magnetic-body core; and inputting the coil assembly body and a putty-like admixture including magnetic powders and a thermosetting resin into an inner cylindrical portion of a die, further including the steps of: pressing the admixture which is inputted into the inner cylindrical portion, applying vibration for giving shear force with respect to the admixture which is inputted into the inner cylindrical portion for decreasing the viscosity of the aforesaid admixture, and thermosetting and forming a magnetic cover portion by heating an integrated object comprised of the admixture which was applied with the vibration and the coil assembly body and by thermally-curing the thermosetting resin included in the admixture.
