Abstract
To restrain damage to an exterior member in a miniaturized coil component.SOLUTION: A coil component 1 includes a base 10 containing a plurality of metal magnetic particles, and a coil conductor including a first winding portion 25a1 and a second winding portion 25b1 that are wound around a coil axis Ax in the base. The base has a first magnetic portion 11 and a second magnetic portion 12. The first magnetic portion is provided outside the coil conductor in a radial direction centered on a coil axis. The second magnetic portion is provided inside the first magnetic portion in the radial direction. In a section obtained by cutting the base along a cut section along the coil axis, a first porosity indicating the area ratio of voids in the first magnetic portion is smaller than a second porosity indicating the area ratio of voids in the second magnetic portion.SELECTED DRAWING: Figure 2
