1. An inductor component comprising:
an element body containing a magnetic material; and
an inductor wire disposed in the element body, the inductor wire including:
a wire main body extending on a predetermined plane, the wire main body being parallel to the predetermined plane and having a dimension that is constant in a width direction perpendicular to an extending direction in which the wire main body extends;
a pad via which the wire main body is to be connected to another wire; and
at least one protrusion protruding, from the wire main body, on the predetermined plane, the protrusion protruding from an edge of the wire main body in the width direction, and
an area ratio of the protrusion to the wire main body as viewed from a direction perpendicular to the predetermined plane being less than or equal to 7.2%,
wherein the dimension is constant between the pad and the protrusion in the width direction perpendicular to the extending direction in which the wire main body extends.
