A coil component including: a first magnetic core including a columnar portion; a second magnetic core having a facing surface which faces one end surface of the columnar portion; a magnetic-gap layer which is constituted by a non-magnetic material, which is arranged between the facing surface and the one end surface, and which forms a magnetic gap between the facing surface and the one end surface; a coil through which the columnar portion is inserted; and a magnetic molded-body which is constituted by a magnetic material and which covers the first magnetic core and the coil, wherein when watching along the axial center direction of the columnar portion, the magnetic-gap layer protrudes to the periphery of the columnar portion.
