In an embodiment, a coil component 10 has a drum core 20 housed in a through hole 32 of a ring core 30, and two types of securing parts are provided in a gap G between an outer circumference of one flange part 24 of the drum core 20 and an inner circumference of the through hole 32. Terminal electrodes 50A, 50B connecting to ends 46A, 46B pulled out from a winding wire 40 wound around the drum core 20 are assembled to the ring core 30. Second securing parts 60A, 60B are arranged to opposite to each other with respect to a center C of the flange part 24, and first securing parts 62A, 62B are provided to cover an outer side of the second securing parts 60A, 60B. A hardness of the second securing part is higher than that of the first securing part.
