Abstract: A motor coil substrate includes a coil substrate including a flexible substrate and coils such that the coils include first wirings formed on a first surface of the flexible substrate and second wirings formed on a second surface of the flexible substrate on the opposite side. The coil substrate is wound N turns where N is an integer of 2 or more in a circumferential direction such that the first surface of the flexible substrate is positioned on an inner circumferential side of the coil substrate, the second surface of the flexible substrate is positioned on an outer circumferential side of the coil substrate, and a gap is formed between an M-th layer where M is an integer equal to or larger than 1 and less than N and an (M+1)-th layer from an inner side of N circumferential layers formed by winding the coil substrate N turns.
