ABSTRACT:
A coil component including a connection part not excessively welded to a terminal electrode. End portion of a conducting wire of a common mode filter is laser-welded, while being held by a holding piece and a surface of the terminal electrode. A portion melted by laser-welding includes a bulge portion which bulges in a direction away from a core. There is provided a lower insulation covering portion between a foundation and the portion corresponding to the end portion of the conducting wire. For the bulge portion, the lower insulation covering portion is provided only between the foundation and the portion corresponding to the end portion of the conducting wire, thereby preventing excessive welding to a terminal electrode.
