  • Patent number: 10116053
    Abstract: Provided is an antenna coil component including a bobbin around which a winding is wound, a base provided at least at one end side of the bobbin, and one or more metal terminals each fixed to the base, at least one metal terminal among these metal terminals including a fixing part for fixing the metal terminal to the base, a mounting part provided at a position away from the fixing part, and a neck part for connecting the fixing part and the mounting part to each other. The neck part has a length in a direction substantially orthogonal to a direction from the fixing part to the mounting part and substantially parallel to surfaces of the mounting part, which is narrower than that of the mounting part. Provided as well are an antenna unit using the antenna coil component, and a method of manufacturing the antenna coil component.
