An electric storage device monitor includes a measurement unit detecting and obtaining a detected value, a power supply switch portion switching a power supply state of the monitor between a monitoring state and a low power consumption state, a wakeup timer to which an actuation time is set and starting counting time in response to switching to the low power consumption state and continuing counting time and outputting an actuation signal if reaching the actuation time, and a control unit. The switch portion switches from the low power consumption state to the monitoring state every time the wakeup timer outputs the actuation signal. The control unit controls the measurement unit to detect and obtain the detected value in the monitoring state, compares the detected value and a reference value, and changes the actuation time according to a comparison result of the detected value and the reference value.
