A coil component includes a first core, a second core, and a base unit in which a housing recess is formed. The second core includes a flat plate section and a leg. The leg extends from one end portion of the flat plate section toward the bottom surface of the housing recess in the axial direction of a coil. The housing recess includes a first space and a second space. A winding core section of the first core is housed in the first space. The second space is a space different from the first space. The leg is housed in the second space. The base unit includes a leg restricting section. The leg restricting section is disposed on the inward side of the leg in the axial direction.

Coil component

A coil component includes a magnetic core having a core portion; an insulation frame housing the magnetic core; an electrode terminal member provided on the insulation frame; and at least one coil, which is formed of an insulatingly coated lead wire and is electrically connected to the electrode terminal member, wherein at least one coil includes a winding portion wound around the insulation frame and the core portion so as to be in contact with a second wall portion and a fifth wall portion of the insulation frame.

A coil component includes: a core having first and second shafts arranged in a line, and first and second opposed members; a case supporting the core and having a housing accommodating the core, and first and second outer walls opposing each other; a coil wound around the first and second shafts; and first and second metal terminals being electrically connected to the coil and being provided at the first and second outer walls, respectively. The first and second opposed members are opposed to each other and sandwich the first and second shafts therebetween.

A coil component having a first coil, a second coil, a third coil, each of which has a different function, an upper flange, and a lower flange, and also including a drum core in which a first winding groove having the first coil wound around is formed, and a base member having a winding shaft provided in a bottom portion, wherein a second winding groove is formed between the lower flange and the bottom portion, and the second coil and the third coil are wound around this second winding groove when the drum core and the base member are assembled together.
