Abstract
An object is to reduce a current detection error of a current sensor while suppressing upsizing of a power conversion device equipped with the current sensor. A power conversion device includes a power conversion circuit; a conductor to transmit current to the circuit; and a coreless current sensor to detect the current. The coreless current sensor includes: a magnetic field detection portion; and a shield portion facing the magnetic field detection portion. The conductor includes: a first conductor portion that passes through a space between the magnetic field detection portion and shield portion; and a second conductor portion connected to the first conductor portion via a first bent portion, and the first bent portion is formed such that the space between the magnetic field detection portion and shield portion is not disposed in a direction perpendicular to a face of the second conductor portion closest to the shield portion.
