To provide a coil component in which compaction and low profile can be achieved easily, and a core can be positioned with high accuracy, and thereby desired characteristics can be obtained reliably.

A pair of bobbins 1 each including a cylindrical winding 2 where a wire 8a for forming a coil 8 is wound around the outer periphery, and terminal blocks 3a, 3b formed at both ends of the winding 2 integrally therewith and each having a terminal 6, planted thereon, to which the end of the wire is entangled, are arranged to face each other, while paralleling the axes of the windings 2, and the legs 11a of a U-shaped core 11 are inserted into the windings 2 from both end sides thereof. Furthermore, engaging parts 4, 5 for determining the relative position in the axial direction and the facing direction, by engaging with the other facing terminal block 3b, 3a are formed in the terminal blocks 3a, 3b.
