Abstract

A current sensor includes a magnetic detector and a first soft magnetic body. The magnetic detector is configured to be subjected to a magnetic flux that is to be generated when a current flows through a conductor along a first axis direction, the magnetic flux being in a second axis direction. The first soft magnetic body includes a first portion, a second portion disposed between the conductor and the first portion, and a third portion magnetically coupling the first portion and the second portion to each other. The first soft magnetic body is spaced from both of the conductor and the magnetic detector, with the first portion, the second portion, and the third portion surrounding the magnetic detector along a first plane orthogonal to the second axis direction.
