Abstract:
1. A coil component comprising: an Mn—Zn-based ferrite core having a winding core part and a pair of flanges arranged at both ends of the winding core part; a wire wound about the winding core part; and a terminal electrode provided with the Mn—Zn-based ferrite core and connected to an end part of the wire, wherein the Mn—Zn-based ferrite core has a surface coated with a glass film; a thickness of the glass film is greatest in a portion that covers an outer side face of the flange; and a thickness of the glass film covering a surface of the winding core part and a thickness of the glass film covering an inner side face of the flange are smaller than a thickness of the glass film covering a periphery of the flange.
