<p>PURPOSE: To provide a thin cordless power station with good power transmission, by improving a soft magnetic material and the shape of a coil. CONSTITUTION: A cordless power station has a pair of coils 3 and 4 opposite to each other and transmits power in a non-contact state through an effect of electromagnetic induction. The coils 3 and 4 are made of plane spiral coil or plane meandering coil with each input part and output part. Then, soft magnetic members 7 and 8 are fitted to the output side of the input/output part or on both outer side. The soft magnetic members 7 and 8 include soft magnetic powder and organic binding material, in which the soft magnetic powder has a mean grain size of 150μm or below in a flat and/or needle-like and/or granular shape, and the soft magnetic layer has a thickness of 0.1 to 5.0mm.</p> |
