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 (30) supplies power to a mobile electronic device (2). The mobile electronic device (2) includes: a cell terminal (60) which outputs and inputs power to/from the mounted secondary cell (30); non-contact information extraction means (20) which performs a magnetic field communication; a loop antenna (26) which transmits/receives a signal using an electromagnetic wave by the non-contact information extraction means (20); and control means (22) which acquires particular information outputted from the non-contact information extraction means (20) and controls charge of the secondary cell (30) according to the acquired particular information. The loop antenna (26) is arranged in the cell terminal (60).
