Coil component

A coil component comprising:

• a core including a winding core portion extending in an axial direction, and a first flange portion and a second flange portion respectively provided at a first end and a second end opposite to each other in the axial direction of the winding core portion;
• a first terminal electrode provided in the first flange portion;
• a second terminal electrode provided in the second flange portion;
• and
• at least one wire wound around the winding core portion, the at least one wire including a core wire made of copper or a copper alloy and an insulating coating film made of resin covering a peripheral surface of the core wire,
• wherein the core wire of the wire includes a first terminal electrically connected to the first terminal electrode and a second terminal electrically connected to the second terminal electrode,
• each of the first flange portion and the second flange portion has a bottom surface facing a mounting surface side,
• each of the first terminal electrode and the second terminal electrode includes a nickel-containing layer made of nickel or a nickel alloy, the nickel-containing layer being provided to cover the bottom surface of each of the first flange portion and the second flange portion, and a tin-containing layer made of tin or a tin alloy located on the nickel-containing layer,
• each of the first terminal and the second terminal includes a contact surface in contact with the nickel-containing layer, a pair of side surfaces adjacent to the contact surface, the pair of side surfaces extending in a direction rising from the nickel-containing layer, and a top surface adjacent to the pair of side surfaces, the top surface facing the contact surface, and
• the pair of side surfaces of at least one of the first terminal and the second terminal has a region out of contact with the tin-containing layer at least on a top surface side.
