SHIELD, NON-CONTACT POWER TRANSMISSION APPARATUS, AND NON-CONTACT POWER RECEPTION APPARATUS

摘要

This shield is capable of suppressing deterioration of transmission efficiency and is also capable of suppressing heat generation of the shield. A shield (10) is a rectangular parallelepiped housing which surrounds coils that generate a magnetic flux due to an electromagnetic force, said housing being configured from a material that can block electricity and magnetism. The shield (10) has one of the two bottom surfaces thereof opened such that power transmission or power reception can be performed between a coil and another coil facing the coil. The shield (10) has one or more slits (15) formed in an unopened bottom surface (12) and/or a side surface (11).
