Abstract
A current sensor has first and second magnetic bodies for magnetic shielding opposed to each other, and a bus bar and a Hall IC disposed between the magnetic bodies. The magnetic bodies are magnetized in directions opposite to each other when a current flows through the bus bar. The Hall IC is disposed at a position at which a magnetic field applied to the Hall IC is weakened by magnetization of the first magnetic body and by magnetization of the second magnetic body.
