ABSTRACT:
A coil assembly comprises a plurality of conductive spiral pattern layers which are piled up via (an) insulating layer(s) on a wafer. The electrical connection between the spiral patterns is established by means of a conductive member, which is a portion of the upper spiral pattern layer, filled in a through-hole which is made in the insulating layer so that the spiral patterns are connected in series to develop a high voltage when the coil assembly is moved in a magnetic field.
