Abstract
A method of manufacturing a coil component includes providing an intermediate body, heating the intermediate body at a first temperature ranging from 100 to 350° C., and after the heating at the first temperature, heating the intermediate body at a higher second temperature ranging from 600 to 900° C. The providing of the intermediate body including (i) preparing a base material having a flat plate shape or a wire shape, (ii) bending the base material to form a conductor portion, (iii) preparing a metal magnetic paste containing a resin and a plurality of metal magnetic particles mainly composed of iron, and (iv) applying a molding pressure to the metal magnetic paste covering the base material to form the intermediate body including a substrate body containing the plurality of metal magnetic particles and the conductor portion. The magnetic base body including an oxide coating film containing iron oxide on a surface of each of the metal magnetic particles.
