Abstract
A Printed Circuit Board (PCB) having a weak magnetic field sensor of the present invention includes a base plate on which a first excitation circuit and a first detection circuit are formed on each of the sides thereof, soft magnetic core bodies laminated on the top and bottom of the base plate, respectively, and formed of a plurality of soft magnetic cores, and outer layers that are laminated on the soft magnetic core bodies, respectively, and on which a second excitation circuit and a second detection circuit connected to the first excitation circuit and the first detection circuit through via holes are formed so as to surround the soft magnetic cores, respectively. The present invention is characterized in that the soft magnetic cores, the excitation circuit and the detection circuit formed on one side of the base plate are perpendicular to the soft magnetic cores, the excitation circuit and the detection circuit formed on the other side of the base plate.
