  • Patent number: 9202620
    Abstract: In a coil component, a shortest distance from a longitudinal wall of a flange portion of a drum core to a wire fixing portion is smaller than a shortest distance of the longitudinal wall to an electrode wire connecting portion by a convex portion formed at the longitudinal wall of the flange portion. That is, since a gap between the flange portion of the drum core and the wire fixing portion is small (or there is no gap), the wire fixing portion can be sufficiently bent. Accordingly, the wire can be securely fixed by a wire fixing portion of a metal terminal.
