1. An inductor component comprising:
a single-layer glass plate of a rectangular parallelepiped shape with a length, a width, and a height, the length being longer than the width, the single-layer glass plate having a bottom surface defined by the length and the width and a top surface positioned on a back side of the bottom surface;
bottom-surface conductors disposed on the bottom surface and top-surface conductors disposed on the top surface;
through wirings each extending through a corresponding one of through holes in the single-layer glass plate;
an underlying insulation layer disposed above the bottom-surface conductors; and
a first terminal electrode and a second terminal electrode disposed above the underlying insulation layer,
the bottom-surface conductors, the top-surface conductors, and the through wirings being electrically connected to each other to constitute a circularly extending wiring that circularly extends around a winding axis parallel to the bottom surface and the length,
the circularly extending wiring, the first terminal electrode, and the second terminal electrode being electrically connected to each other to constitute an inductor element,
the single-layer glass plate containing cerium oxide, and
the single-layer glass plate including a grooved portion on the bottom surface, wherein the bottom-surface conductors are wound around the bottom surface along the grooved portion.
