Abstract: 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.
