Abstract
A current detection device that detects a current flowing through a target bus bar based on a magnetic flux in the periphery of the target bus bar, the target bus bar being at least one of a plurality of bus bars arranged in parallel. An adjacent bus bar is configured by including a first extending section that is arranged on a first direction side on one side of an orthogonal direction with respect to a magnetic flux detection plane, and extends in a first extending direction parallel to a magnetic flux detection plane, and a second extending section that is bent at one end portion of the first extending section in the first extending direction toward the first direction side, and extends in a second extending direction that crosses the magnetic flux detection plane. A detection portion of the target bus bar overlaps with the first extending section.
