Claim 0:
1. A coil component comprising:
a drum core that includes a winding shaft and a first flange part provided at one end of the winding shaft in an axial direction;
a coil that includes a winding part constituted by a conductive wire being wound around the winding shaft, and a pair of lead parts constituted by the conductive wire being bent from an end of the winding part onto a first side face of the first flange part as viewed toward the first side face in a direction orthogonal to an axis of the winding shaft, said first side face connecting an inner face on which the winding shaft is provided, and an outer face opposite the inner face in the axial direction, of the first flange part; and
a pair of external electrodes that are provided on the outer face of the first flange part, and connected to the pair of lead parts;
wherein, among distances between the first side face of the first flange part on a plane on which the pair of lead parts are disposed, and any outermost wound part of the winding part, a shortest distance is a distance at a first point on the first side face of the first flange part,
wherein the shortest distance at the first point is shorter than a shortest distance between a second side face, which is a face opposite the first side face across the winding shaft, of the first flange part, and any outermost wound part of the winding part, at a symmetry point of the first point, on the second side face with respect to a center point of the first flange part,
wherein a bottom face of the winding shaft at the one end of the winding shaft has dimensions defined by a length A in a long direction and a length B in a short direction, wherein a value A/B is 1.1 or greater but no greater than 2.6,
wherein a distance between an axial center of the winding shaft and the first side face, on which the lead parts are provided, of the first flange part is shorter than a distance between the axial center of the winding shaft and the second side face of the first flange part as viewed in the axial direction of the winding shaft, and
wherein the shortest distance between the first side face of the first flange part and the outermost wound part of the winding part is equal to or smaller than a thickness of the conductive wire in a direction perpendicular to an axial center of the winding shaft.
