TRANSMISSION COIL, CONTACTLESS CHARGER, CONTACTLESS RECHARGEABLE EQUIPMENT, MANUFACTURING METHOD OF TRANSMISSION COIL AND CONTACTLESS POWER TRANSMISSION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To realize miniaturization and cost reduction of the contactless charger. PSOLUTION: A transmission coil 3 is equipped with a transmission coil body 4, and a core body 3 wherein a magnetic shield 32 disposed outside the transmission coil body 4 is projected in a center core 31 provided inside the transmission coil body 4. The center core 31 of the core body 3 and the magnetic shield 32 are formed integrally to one component by a molded item formed by fixing a magnetic powder 6 by means of a binder resin 7. A contactless charger 2 with the built-in transmission coil 3, a contactless rechargeable equipment 5, a manufacturing method of the transmission coil, and a contactless power transmission system, are also provided.
