<p>PURPOSE:To improve the transmission efficiency of power by reducing the reluctance of a magnetic circuit. CONSTITUTION:In an electromagnetic induction charging system, in which power transmission sections 4, 5 disposed into the casing of a power transmission device 1 and power receiving sections 7, 8 arranged into the casing of a power receiver 6 are faced oppositely through the box bodies, a magnetic circuit is constituted among the power transmission devices 4, 5 and the power receiving sections 7, 8, and a secondary cell mounted to the power receiver 6 is charged by a transmission signal from the power transmission device 1, sections configuring the magnetic circuit in the box bodies are formed of ferrite resins 14, 15.</p> |
