摘要： A coil substrate includes a flexible substrate having a first end and a second end on the opposite side with respect to the first end, and coils formed on the flexible substrate in substantially one row between the first end and the second end of the flexible substrate such that each of the coils has a center space and wirings surrounding the center space. The wirings in each of the coils include parallel wirings formed substantially parallel to a row direction extending from the first end toward the second end and perpendicular wirings formed substantially perpendicular to the row direction, and the coils are formed such that a thickness of the perpendicular wirings is greater than a thickness of the parallel wirings.

摘要： A coil substrate for a motor includes a flexible substrate, and multiple coils formed on a surface of the flexible substrate. Each of the coils has a wiring having first wiring portions and second wiring portions extending from the first wirings respectively and is formed such that the first wiring portions extend parallel with respect to each other and that the second wiring portions extend not parallel to the first wirings, and the flexible substrate is formed to be formed around a magnet of a motor such that the first wiring portions form an angle that is substantially perpendicular to a rotation direction of the motor.
