Abstract
A method for manufacturing a coil component includes: providing multiple metal magnetic grains; preparing a magnetic body paste by mixing the multiple metal magnetic grains, a binder resin containing a resinate having at least one element selected from the group consisting of Si, Al, Cr, Mg, Ti, and Zr, and a solvent; forming a compact using the magnetic body paste; heat-treating the compact to form, on surfaces of the metal magnetic grains, bonding parts constituted by an amorphous oxide containing carbon and the at least one element, thereby forming a magnetic base body wherein the multiple metal magnetic grains are bonded via the bonding parts; forming a coil that includes a metal conductor; and forming external electrodes on surfaces of the magnetic base body and connecting end parts of the coil to the external electrodes, respectively.
