Coil component and manufacturing method thereof
First Claim
1. A coil component comprising:
- a drum core including a pair of flange portions and a winding core portion positioned between the flange portions, each of the flange portions having a first adhesion surface substantially parallel with an axis of the winding core portion;
a plate-shaped core having a second adhesion surface adhered to the first adhesion surfaces of the flange portions;
a plurality of terminal electrodes formed on the flange portions; and
a plurality of wires wound around the winding core portion, each end of the wires being electrically connected to an associated one of the terminal electrodes, whereineach of the flange portions further has an inner side surface connected to the winding core portion and an outer side surface opposite to the inner side surface,the outer side surface of each of the flange portions has a plurality of ridges and at least one groove,the plurality of ridges are arranged in a width direction of flange portions,the plurality of ridges include a first ridge positioned at one end of the outer side surface in the width direction and a second ridge positioned at other end of the outer side surface in the width direction,edges of the first and second ridges constitute edges of the flange portions in the width direction,the terminal electrodes are directly formed on at least the ridges of the outer side surfaces of each of the flange portions without an intervention of an insulating material such that the terminal electrodes are isolated from each other by the groove, andthe second adhesion surface of the plate-shaped core has an area overlapping with the groove, the area being exposed without being covered with the first adhesion surfaces of the flange portions.
