  • Patent number: 11527351
    Abstract: A surface-mount inductor includes an element assembly having a core, a coil, and a magnetic material; and a pair of external terminals on a mounting surface of the element assembly. The core has a base portion and a columnar portion on an upper surface of the base portion. The coil is disposed on the base portion, and has a wound portion on the columnar portion, and a pair of extended portions extended from the wound portion. The base portion has at least one ridge portion at which the upper surface and a side surface are in linear contact with each other. The pair of extended portions are each disposed such that a flat surface portion connected to a flat surface portion disposed at an inner side portion of a conductive wire located at an outer peripheral portion of the wound portion is close to the ridge portion.
