1. An inductor component comprising:
an element body formed by stacking a plurality of insulating layers, the insulating layers including a filler material composed of quartz and a glass material; and
a coil provided in the element body, the coil including a coil conductor layer wound on each of the insulating layers,
wherein
an aspect ratio of the coil conductor layer is about 1.0 or more, and the aspect ratio is defined by a thickness of the coil conductor layer in a coil axis direction divided by a width of the coil conductor layer, and
a side surface of the coil conductor layer has one protrusion or is smooth in a cross section perpendicular to a direction in which the coil conductor layer extends.
