Abstract
A coil substrate includes a flexible substrate, and a coil including a first wiring formed on a first surface of the flexible substrate and a second wiring formed on a second surface of the flexible substrate on the opposite side with respect to the first surface of the flexible substrate. The coil is formed such that an inter-wiring distance of the first wiring formed on the first surface of the flexible substrate is larger than an inter-wiring distance of the second wiring formed on the second surface of the flexible substrate.

A coil substrate, comprising:
- a flexible substrate;
- and
- a coil comprising a first wiring formed on a first surface of the flexible substrate and a second wiring formed on a second surface of the flexible substrate on an opposite side with respect to the first surface of the flexible substrate,
- wherein the coil is formed such that an inter-wiring distance of the first wiring formed on the first surface of the flexible substrate is larger than an inter-wiring distance of the second wiring formed on the second surface of the flexible substrate.
A coil substrate, comprising:
- a flexible substrate;
- and
- a plurality of coils each comprising a first wiring formed on a first surface of the flexible substrate and a second wiring formed on a second surface of the flexible substrate on an opposite side with respect to the first surface of the flexible substrate,
- wherein the plurality of coils is formed such that an inter-wiring distance of the first wiring formed on the first surface of the flexible substrate is larger than an inter-wiring distance of the second wiring formed on the second surface of the flexible substrate.
A motor coil substrate, comprising:
- a coil substrate wound in a cylindrical shape and comprising a flexible substrate and at least one coil comprising a first wiring formed on a first surface of the flexible substrate and a second wiring formed on a second surface of the flexible substrate on an opposite side with respect to the first surface of the flexible substrate,
- wherein the coil substrate is formed such that the first surface of the flexible substrate is positioned on an inner peripheral side of the cylindrical shape and that the second surface of the flexible substrate is positioned on an outer peripheral side of the cylindrical shape, and the coil substrate is wound in the cylindrical shape such that a distance between top portions of the first wiring on the first surface of the flexible substrate is substantially equal to a distance between bottom portions of the second wiring on the second surface of the flexible substrate.
