Abstract
A coil component includes: a magnetic base body formed by metal magnetic grains containing Fe, Si, and Cr, whose intensity ratio (I/I) of the strongest line intensity (I) in a range of wavenumbers 650 to 750 cm, to the strongest line intensity (I) in a range of wavenumbers 400 to 450 cm, in a Raman spectrum measured at the center part is 2 or higher, and which also has a part on the surface side of the center part where the intensity ratio (I/I) in a Raman spectrum is under 2; and a conductor placed inside or on the surface of the magnetic base body. The magnetic base body is constituted by a powder magnetic core made to have excellent electrical insulating property and high magnetic permeability.
