摘要： A current detection apparatus includes a magnetic core having a ring shape with a gap and a center opening portion through which a current path is disposed, and a magnetic sensor including a magnetic sensing element such as a Hall effect element arranged in the gap. When a current flows through the current path, the magnetic core generates magnetic flux therein so that magnetic field is generated in the gap. The magnetic sensor outputs different electrical signals, each of which is measured in a different measurement range and corresponds to intensity of the magnetic field in the gap. The current detection apparatus measures the current based on the electrical signals outputted from the magnetic sensor.
