Coil component
First Claim
1. A coil component comprising:
- a wire having a helical shape, the wire includinga central conductor having a linear shape, andan insulating coating layer that covers a peripheral surface of the central conductor; and
a terminal electrode having a connection part that is electrically connected to the central conductor in an end portion of the wire;
wherein the connection part of the terminal electrode includesa receiving part that receives the end portion of the wire, anda welding part that extends from the receiving part via a fold-back part so as to face the receiving part,wherein the wire is sandwiched between the receiving part and the welding part and the central conductor thereof is welded to the welding part in a coating layer removed portion of the wire, from which the insulating coating layer is removed,the end portion of the wire including a first portion in contact with the receiving part and a second portion extending from the first portion and having a distal end portion,the coating layer removed portion is provided only on an upper side area of the wire within the first portion and defined by the insulating coating layer of the second portion, the upper side area being opposite to a lower side area of the wire, which is in contact with the receiving portion, the insulating coating layer being present in the lower side area within the first portion of the wire, andwherein the distal end portion of the wire protrudes from a space between the receiving part and the welding part, with the insulating coating layer remaining at least on an area of the distal end portion opposite to an area in contact with the receiving part.

Abstract
A coil component including a wire has a central conductor and an insulating coating layer, and a terminal electrode has a connection part that is electrically connected to the central conductor. The connection part includes a receiving part that receives an end portion of the wire, and a welding part that extends from the receiving part via a fold-back part so as to face the receiving part. The wire becomes sandwiched between the receiving part and the welding part. The central conductor is welded to the welding part in the portion from which the insulating coating layer is removed. The distal end portion of the wire protrudes from the space between the receiving part and the welding part, with the insulating coating layer remaining on the distal end portion.
