COIL COMPONENT

Abstract: one object is to inhibit magnetic flux from concentrating in the region of the base body near the end of the inner peripheral surface of the coil conductor in the height direction. a coil component in one aspect includes a base body containing metal magnetic particles and a coil conductor including a winding portion. the base body includes a core portion positioned inside the winding portion, one end portion covering one end surface of the winding portion, and another end portion covering another end surface of the winding portion. the core portion includes a core center portion at the center. an average particle size of metal magnetic particles contained in the one end portion and an average particle size of metal magnetic particles contained in the other end portion are smaller than an average particle size of metal magnetic particles contained in the core center portion.
