    • PROBLEM TO BE SOLVED: To display more accurately the charging state of a secondary battery by a simple constitution. SOLUTION: This display method has the secondary battery 2, a power generation means 1 for supplying the power to the secondary battery 2, a voltage detection circuit A 4 for detecting a plurality of voltage values including a prescribed voltage value (for example 1.2 V) of the secondary battery 2 to which the power is supplied by the power generation means 1, a timer A 13 for clocking the time when a voltage value over 1.2 V is detected continuously by the voltage detection circuit A 4, a timer B 14 for clocking a prescribed time from the point of time when the time clocked by the timer A 13 reaches a prescribed time, and a charging state display part 11 for displaying the charging state of the secondary battery 2 based on one hour clocked by the timer A 13 and on one hour clocked by the timer B 14. Hereby, when estimating the charging state by using the voltage value of the secondary battery 2, the estimation is not influenced by sudden fluctuation of the voltage value or the like.
