Abstract
A current sensor (current detection device)includes a conductorthrough which measurement-target current flows, a magnetic sensorthat detects magnetic fields generated by current flowing through the conductor and a packagethat, together with at least part of the conductor, separates the magnetic sensor from the conductor and covers and seals in their outer surfaces. Together with a curved portionof the conductor, the package separates, from the conductor through which measurement-target current flows, the magnetic sensor that detects magnetic fields generated by current flowing through the conductor and covers and seals in their outer surfaces so that an interface that can spread in the package, in which the magnetic sensor is embedded, from its boundaries with it is not formed; therefore, a high withstand voltage can be obtained.
