PURPOSE: A coil product for electronic components is provided to combine a mechanical piece on a core having an insulating film, thereby minimizing faults caused by a dielectric breakdown. CONSTITUTION: A coil product for electronic components comprises a core(110) having an insulating film(111) on the outer surface thereof; and a coil winding the core. The coil product for electronic components includes a mechanical piece for a high withstand voltage, which is provided inside of the core. The mechanical piece for a high withstand voltage includes a first body(121) and a second body(122) which are mated with each other. Each of the first and second bodies has a rim part(11) and a spaced protrusion part(22) that have circular brims. The coil contacts and winds the mechanical piece for a high withstand voltage and the core. |
