Abstract
A current sensor is configured to detect a current flowing through an electrical conductor. The current sensor includes a core and a coil wound around the core. The core has a hollow configure to allow the electrical conductor to pass through the hollow. The core substantially has a C-shape haying a gap connected to the hollow. At least a part of the gap of the core is located inside the coil. This current sensor suppresses the influence of external noise.
