Method of manufacturing coil and coil device

摘要

A thin film made of a conductive material is formed on one surface of a long-sheet-shaped flexible base. The flexible base formed with the thin film made of the conductive material is wound in a roll shape to fabricate an original roll of coils. The flexible base formed with the thin film made of the conductive material is unwound from the original roll of coils, and rewound around an outer periphery of a core to fabricate a wound body. The wound body is cut in a direction orthogonal to the longitudinal direction of the core to make a coil intermediary body. A cut surface of the coil intermediate body which is cut from the wound body is lapped. Lead wires are attached to both ends of a winding section comprised of the conductive material within the coil intermediary body. The foregoing steps are performed in sequence to manufacture a coil.
