Abstract
A coil component according to one or more embodiments of the invention includes a base body containing a plurality of metal magnetic particles, a coil conductor, and an external electrode. In one or more embodiments, the coil conductor has a coil portion disposed inside the base body, and an end surface exposed from a first surface of the base body. The coil conductor is configured such that the ratio of the dimension of a section of the coil portion in a short axis direction to the dimension of the end surface in a short axis direction is 0.5 to 0.95, the section of the coil portion is orthogonal to the direction in which current flows through the coil portion. In one or more embodiments, the external electrode is provided on the first surface such that it is connected to the end surface of the lead-out portion.
