A main body case on an electronic appliance side is provided with an external terminal. Within the main body case, an internal terminal is arranged opposite to the external terminal. The internal terminal is supported by a compression coiled spring in a conical form. The internal terminal is connected to a secondary battery, and the secondary battery is connected to an electronic circuit for an electronic appliance. A magnet is provided at a tip of a charger, and charger side-terminals are attached on both sides of the magnet. The charger side-terminal is connected to a primary battery internally provided in the charger. When the magnet of the charger is fitted with a groove of the external terminal, the internal terminal is attracted by a magnetic force and contacted with the external terminal. Due to this, the charger side-terminal and the internal terminal are brought into electrical connection through the external terminal, enabling charging.
