PROBLEM TO BE SOLVED: To provide a battery exhaustion display apparatus capable of facilitating recognition as to whether a battery is short of voltage or not. SOLUTION: The battery exhaustion display apparatus includes both a lower-bound voltage detection circuit 11 for measuring an output voltage of a battery B, detecting the state not exceeding a prescribed lower-bound voltage value in which the output voltage is greater than a zero volt, and outputting the state of detection not exceeding the prescribed lower-bound voltage value and a display circuit 12 for turning an irreversible display body 5 into a display state through the use of battery output on the basis of the state of detection from the lower-bound voltage detection circuit 11. The irreversible display body 5 is made of a heat discoloration material. COPYRIGHT: (C)2007,JPO&INPIT
