CURRENT SENSOR, METHOD OF MEASURING CURRENT, AND SWITCH CIRCUIT

摘要

A current sensor, comprises a substrate formed in a multi-layer structure of two layers or more, through-holes provided in the substrate so as to pass from the front surface to the rear surface thereof, a coil formed by connecting the wires on the front and rear surfaces to each other through the through-holes, and a wiring pattern disposed so as to pass through the inside of the coil, whereby a voltage generating at both ends of the coil when a current flows through the wiring pattern can be detected.
