1. A coil component, comprising:
a magnetic base body formed by metal magnetic grains containing Fe, Si, and Cr, whose intensity ratio (IM/IH) of a strongest line intensity (IM) in a range of wavenumbers 650 to 750 cm−1, to a strongest line intensity (IH) in a range of wavenumbers 400 to 450 cm−1, in a Raman spectrum measured at a center part of the magnetic base body is 2 or higher, and which also has a part on a surface side of the center part where the intensity ratio (IM/IH) in a Raman spectrum is under 2; and
a conductor placed inside or on a surface of the magnetic base body.
