Electromagnetic induction sensor, overlay member for electromagnetic induction sensor, and manufacturing method of electromagnetic induction sensor

摘要

Disclosed herein is an electromagnetic induction sensor that is used with a position indicator and includes coils for electromagnetic coupling with the position indicator. The electromagnetic induction sensor includes: a sensor board main body that includes an insulating substrate and a surface sheet attached to a side of a first surface of the insulating substrate, on which side a position is indicated by the position indicator; at least part of conductors forming the coils being formed on a second surface of the insulating substrate opposite from the first surface; and an overlay member that includes a magnetic powder material layer and is adhered to the side of the second surface of the sensor board main body.
