发明名称 MAGNETIC SENSOR AND CURRENT SENSOR INCLUDING THE SAME
摘要 Disclosed herein is a magnetic sensor including: a first core made of a first soft magnetic material, the first core having first and second connection surfaces; a second core made of a second soft magnetic material different from the first soft magnetic material, the second core having a third connection surface facing the first connection surface and a fourth connection surface facing the second connection surface; and a coil wound around the first core between the first connection surface and the second connection surface. The first core reaches magnetic saturation at a higher magnetic field intensity than that of the second core, and the second core has a higher magnetic permeability than that of the first core.
