1. An inductor comprising:
a base body having a mounting surface facing a circuit board, a top surface opposed to the mounting surface, and a first end surface connecting between the mounting surface and the top surface;
a first external electrode provided to the mounting surface of the base body;
a second external electrode provided to the mounting surface, the second external electrode being spaced from the first external electrode in a length direction perpendicular to the first end surface; and
a conductor disposed inside the base body, the conductor extending linearly from the first external electrode to the second external electrode in plan view from a thickness direction perpendicular to the mounting surface, one end of the conductor being exposed from the mounting surface and connected to the first external electrode, the other end of the conductor being exposed from the mounting surface and connected to the second external electrode,
wherein in front view from a width direction perpendicular to the thickness direction and the length direction, the base body is partitioned into a first region and a second region, the first region being enclosed by the conductor and the mounting surface, the second region being the rest of the base body,
wherein the first region has a first area, and the second region has a second area, and a ratio of the second area to the first area is within a range of 0.95 to 1.1, and
wherein the conductor contains a conductive material having a higher electric conductivity than a material of the first external electrode.
