Abstract
It is possible to prevent charge of an incompatible secondary cell while suppressing the size of a mobile electronic device and a secondary cell without increasing power consumption so as to prevent damage of the secondary cell or the mobile electronic device by charge. A detachable secondary cell () supplies power to a mobile electronic device (). The mobile electronic device () includes: a cell terminal () which outputs and inputs power to/from the mounted secondary cell (); non-contact information extraction means () which performs a magnetic field communication; a loop antenna () which transmits/receives a signal using an electromagnetic wave by the non-contact information extraction means (); and control means () which acquires particular information outputted from the non-contact information extraction means () and controls charge of the secondary cell () according to the acquired particular information. The loop antenna () is arranged in the cell terminal ().
