It is detected promptly that an electric storage device is used in an improper condition that a monitor cannot receive an actuation signal from a load side. Accordingly, the electric storage device does not become in an abnormal state. A monitor 30 monitors a state of a secondary battery 10 that is an electric storage device. The monitor 30 includes a CPU 31, a measurement unit 41, and a wakeup timer 35. The measurement unit detects the state of the secondary battery 10. The wakeup timer 35 counts time. Every time the wakeup timer 35 reaches a certain set time, the monitor 30 is actuated from a sleep state and therefore, the monitor 30 is actuated with every certain actuation period T. The measurement unit 41 detects values of the battery 10 and the CPU 31 determines if the value detected by the measurement unit 41 is changed from a previous detected value every time the monitor 30 is actuated. If determining that the value is changed, the CPU 31 changes the actuation period T.
