Abstract

PURPOSE:To achieve miniaturization of a composite coil by a method wherein multiple coils whose axial lines are parallel to each other but slightly out of line between neighboring coils are mutually superposed in their axial direction. CONSTITUTION:The axial line C1 of coil L1 is parallel with the axial line C2 of coil L2, and further the axial line C1 is in line with the center of the L2's winding pile, and the axial line C2 of coil L2 is in line with the center of the L1's winding pile. With this configuration, the center of the magnetic flux generated by coil L2 passes the center of the L1's winding layer. Therefore, coupling between coils is almost null of the theoretical base, so that coupling between coils L1 and L2 is almost null even if the distance S1 between these coils is extremely reduced. Thus, these coils are independent each, and miniaturization of a composite coil can be achieved.
