Abstract

An inductor array of the invention includes a magnetic base body, a first internal conductor within the base body, and a second internal conductor adjacent to the first internal conductor. The first and second internal conductors are arranged along a reference axis. The base body includes an inter-conductor region between the first and second internal conductors. The inter-conductor region has a first section cut along a reference plane including the reference axis, and a first reference axis direction dimension of the first section in the reference axis direction may be less than double a shortest distance between the first internal conductor and a surface of the base body in the reference plane. A first aspect ratio of the first section, which is a ratio of a first orthogonal direction dimension in a direction orthogonal to the reference axis to the first reference axis direction dimension, may be less than 1.
