Title:
ELECTROMAGNET, CAMERA-LENS DRIVING METHOD, AND ELECTROMAGNET MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/079773
Kind Code:
A1
Abstract:
This electromagnet (1) comprises the following: a laminate (10) comprising a plurality of substrate layers (11 through 14) laminated together; a coil comprising planar coil conductors (12A through 14A) each formed on one principal surface of one of the substrate layers (12 through 14); and dummy patterns (21 through 23) that, in a planar view, are formed along at least parts of the coil, outside the planar coil conductors (12A through 14A) on the substrate layers (12 to 14), and are electrically independent. This results in an electromagnet that makes it possible to increase the strength of the electromagnetic force caused by current flowing through the coil.
