保つことができる。As described above, according to the present invention, when the secondary coil for electromagnetic induction coupling with the primary coil on the charger side is built in, the inner bottom surface of the equipment body and the internal parts of the equipment are incorporated. Since the coil bobbin of the secondary coil disposed between the housing and the chassis, which is provided between the housing and the chassis, is formed integrally with the housing or the chassis, an independent coil bobbin is not required. It does not require an elastic body or the like for positioning and fixing, which reduces the number of parts and improves assemblability. The induction transmission efficiency between the side coil and the secondary coil can be kept at a high value.
