Abstract
To provide a further miniaturized and densified current detection device or a power conversion apparatus including the same. A current detection device or a power conversion apparatus according to the present invention includes: a plurality of conductors corresponding to currents of a plurality of phases; and a current sensor. The plurality of conductors is formed so as to have a conductor portion in which the currents flowing in the plurality of conductors, respectively, are substantially parallel. In a cross section in a direction perpendicular to a flow direction of the current of the conductor portion, the current sensor is arranged in a region sandwiched between the plurality of conductor portions, and outputs information on a current flowing in the conductor based on a combination of magnetic field vectors generated by the plurality of currents.
