Abstract

A coil assembly (100) comprises a plurality of coil layers (S1 to S4) which are stacked on one another in a stacking direction (Z). Each of the coil layers includes a plurality of planar coils (1 to 8) which are wound in a planar direction (X-Y) perpendicular to the stacking direction and electrically connected in parallel to each other between the coil layers. The coil assembly also includes a plurality of coil units (a to d) each of which includes at least one of the planar coils disposed on a respective one of the coil layers. The plurality of coil units are connected in parallel to each other. The coil layers include a first pitch coil layer (S1, S2) and a second coil pitch layer (S3, S4). The first pitch coil layer has disposed thereon wound conductive wires, two adjacent ones of which are arranged at a pitch (p1) away from each other. The second pitch coil layer has disposed thereon wound conductive wires, two adjacent ones of which are arranged at a pitch (p2, p3) away from each other, the first pitch being different from the second pitch. The pitch of the first pitch coil layer is greater than that of the second pitch coil layer.
