1. A coil component comprising: a core part including: a winding shaft; and a flange part provided on an axial-direction end of the winding shaft, wherein the flange part has: an exterior face on an opposite side of the winding shaft, a pair of a first side face and a second side face that are adjoining the exterior face and located opposite to each other, and first and second groove parts provided on the exterior face, which are isolated from each other or connected to each other on the exterior face, wherein the first and second groove parts extend to the first side face and the second side face, respectively, via a cut-out part provided on each of the first side face and the second side, wherein the first and second groove parts each have a planar surface perpendicular to the axial direction, wherein a thickness of the flange part measured at the planar surface in the axial direction is less than a thickness of the flange part measured at a surface of the exterior face, other than the planar surface, perpendicular to the axial direction; a coil part including: a winding part constituted by a conductor with an insulating film, which is wound around the winding shaft; and a pair of lead parts that are portions of the conductor led out from the winding part; and a pair of terminal parts formed on the exterior face of the flange part, wherein one of the pair of lead parts is led in from the cut-out part on the first side face of the flange part and fitted inside the first groove part provided on the exterior face, and included in one of the pair of terminal parts, and another of the pair of lead parts is led in from the cut-out part on the second side face of the flange part and fitted inside the second groove part provided on the exterior face, and included in another of the pair of terminal parts, wherein the winding shaft is provided in a manner that a center axis of the winding shaft is offset from a center of the exterior face; and the first and second groove parts are provided in a manner offset in a direction opposite to a direction in which the center axis of the winding shaft is offset from the center of the exterior face.
