PURPOSE:To indicate the completion of charge without detection errors and delay in time with a simple construction by indicating changes in the temperature due to internal heat generation of a battery through a temperature indicating material. CONSTITUTION:A temperature indicating material 5 is provided on the outer surface of a battery 2 to indicate temperature changes as set higher than the temperature range of the battery at the start of charge but lower than the temperature at which the battery deteriorates by overcharging. Thus, the charging of the battery is indicated without detection error and delay in time with such a simple construction as using a temperature indicating material with a small heat capacity allowed to contact the battery directly.
