## Abstract

An inductor component includes a base having a columnar shape and including a mounting surface parallel with a length direction being a longitudinal direction of the columnar shape and with a width direction orthogonal to the length direction, inductor wiring arranged inside the base, a first outer electrode connected to the inductor wiring and disposed on the mounting surface, and a second outer electrode connected to the inductor wiring and disposed on the mounting surface, the first outer electrode and the second outer electrode arranged in the length direction. When a maximum dimension of the mounting surface in the length direction is L, a maximum dimension of the first outer electrode in the width direction is a, and a maximum dimension of the second outer electrode in the width direction is b, a≤L/2<W and b≤L/2<W.
