Coil substrate, motor coil substrate, and motor

A coil substrate, comprising:

• a flexible substrate having a first surface and a second surface on an opposite side with respect to the first surface;
• and
• a plurality of coils formed on the flexible substrate such that each of the coils includes a plurality of wirings formed on the first surface of the flexible substrate and a plurality of wirings formed on the second surface of the flexible substrate,
• wherein the plurality of coils includes an N-th coil forming an N-th phase and an (N+1)-th coil formed adjacent to the N-th coil and forming an (N+1)-th phase different from the N-th phase, and each of the coils is formed such that an inter-wiring distance between the wirings forming the N-th coil and the wirings forming the (N+1)-th coil is larger than an inter-wiring distance between the wirings forming the N-th coil, that the inter-wiring distance between the wirings forming the N-th coil and the wirings forming the (N+1)-th coil is larger than an inter-wiring distance between the wirings forming the (N+1)-th coil and that the inter-wiring distance between the wirings forming the N-th coil and the wirings forming the (N+1)-th coil on the first surface of the flexible substrate is larger than the inter-wiring distance between the wirings forming the N-th coil and the wirings forming the (N+1)-th coil on the second surface of the flexible substrate.
