A coil component including: a core that is configured with a shaft and first and second flanges, the first and second flanges being formed at first and second opposite ends of the shaft; first and second wires that are wound around the shaft; and a plurality of metal terminals to which both wire ends of each of the first and second wires are connected, respectively. A notch is formed in both ends in a first direction of an opposite surface of each of the first and second flanges. The opposite surface faces a mounting surface on which the coil component is mounted. The first direction is perpendicular to an axial direction of the shaft. At least part of each of the plurality of metal terminals is disposed in the notch.

Coil component

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.
