Claim 0:
1. A coil component, comprising:
an element body part which is formed by materials that include a magnetic material;
a coil which is built into the element body part and formed by a conductor;
a first external electrode which is provided at least on a first face, among all surfaces, of the element body part at a position closer to a first side edge of the first face, than to a center between the first side edge and a second side edge of the first face opposite the first side edge in a direction intersecting an axis of the coil as viewed in an axial direction of the coil,
and which is electrically connected to the coil; and
a second external electrode which is provided at least on the first face, among all surfaces, of the element body part at a position closer to the second side edge of the first face, than to the center between the first side edge and the second side edge,
and which is electrically connected to the coil;
wherein the first external electrode has a first joining part, which is physically and electrically joined to the first face, and a first non-joining part, which is a part other than the first joining part and entirely faces in a thickness direction the first face constituted by the magnetic material but is positioned away from the first face in a state where the coil component is not mounted on a circuit board,
wherein the first non-joining part is positioned closer to the second external electrode on the first face than is the first joining part,
wherein the first external electrode is formed in a manner so as to extend from the first face, via a second face that connects to the first face along the first side edge of the first face, to a fourth face opposite the first face, of the element body part; and
wherein the first external electrode has a third joining part, which is physically and electrically joined to the fourth face,
and a third non-joining part, which is a part other than the third joining part and faces the fourth face but is positioned away from the fourth face in a state where the coil component is not mounted on a circuit board,
wherein the third non-joining part is positioned closer to the second external electrode on the fourth face than is the third joining part.
