A coil component includes a wire; a core having a winding core around which the wire is wound and a flange portion provided at an end portion of the winding core in an axial direction; and a terminal electrode to which the wire is connected and that is provided on the flange portion. The terminal electrode has a projecting portion that sticks out in the axial direction relative to the flange portion. The projecting portion has a flat surface along which the wire is thermocompression-bonded. Thermocompression bonding of the wire is performed in a state where an interval between a head surface of a heater chip and the flat surface becomes narrower from a flange portion side toward a front end side of the projecting portion. A degree of crushing of the wire decreases from the front end side toward the flange portion side of the projecting portion.
