Abstract
A current detection device of an embodiment includes a conductor, a first magnetic field detector, a second magnetic field detector, and a conductive film. The conductor includes a first region, a second region, and a third region connecting an edge of the first region and an edge of the second region. The first magnetic field detector is disposed between the first and second regions. The second magnetic field detector is disposed opposite to the first magnetic field detector with respect to the third region. The conductive film is bonded to a conductor layer including a slit having a width larger than each of widths of magneto-sensitive parts of the first and second magnetic field detectors and covers the slit, the conductor layer being provided between the conductor and each of the first and second magnetic field detectors.
