Zusammenfassung:	PURPOSE:To provide the IC card with solar battery capable of providing the power of writing data for an EEPROM offline. CONSTITUTION:A power supply 20 providing the auxiliary power for writing is provided on a EEPROM 12c. Normally, the IC card is operated on the power of a solar battery 4. Only when the data writing to the EEPROM 12c, the solar battery 4 and the power supply 20 are serially connected based on the control of the CPU 11, and the writing power to the EEPROM 12c is provided by the serial power.
