<p>A current sensor has first (30A) and second magnetic bodies (30B) for magnetic shielding opposed to each other, and a bus bar (10) and a Hall IC (20) disposed between the magnetic bodies. The magnetic bodies are magnetized in directions opposite to each other when a current flows through the bus bar, and the Hall IC is disposed at a position at which a magnetic field applied to the Hall IC is weakened by a magnetic field generated by magnetization of the first magnetic body and a magnetic field generated by magnetization of the second magnetic body.</p> |
