1. An inductor component comprising:
an element body comprising an insulator, the element body having a mounting surface and a top surface that are parallel to each other, a first end surface and a second end surface that are parallel to each other, and a first side surface and a second side surface that are parallel to each other;
an inductor wiring disposed inside the element body, the inductor wiring being shaped like a coil wound inside the element body, and a center axis of winding of the inductor wiring being perpendicular to the first side surface;
a first lead-out electrode connected to a first end of the inductor wiring, the first lead-out electrode having a columnar shape that extends in a direction perpendicular to the mounting surface and being exposed from the first end surface and the first side surface, an upper end of the first lead-out electrode being flush with an upper surface of a straight part of the inductor wiring; and
a second lead-out electrode connected to a second end of the inductor wiring,
wherein
part of the first lead-out electrode and part of the second lead-out electrode are exposed from the mounting surface,
a portion of the first side surface abuts and extends along the first lead-out electrode from an upper surface of the first lead-out electrode to the mounting surface of the element body,
a portion of the first end surface abuts and extends along the first lead-out electrode from the upper surface of the first lead-out electrode to the mounting surface of the element body, and
the first lead-out electrode is not exposed from the second end surface and the second side surface.
