To provide a small-sized indicator for measuring a movement quantity capable of graphing and displaying the movement quantity per unit time in a day or a pattern of the movement quantity by detecting movement of an animal.

An indicator body is provided with a vibration sensor for detecting the movement; a control device performing each processing for determining existence of a pulse signal outputted from the vibration sensor in a prescribed unit second interval, counting the number of unit second intervals having a pulse signal 'existence', allowing a memory to store the number, when the counted values are integrated to reach a prescribed unit minute interval, accumulating the values one by one as the movement quantity in a present unit time in the unit times determined by dividing one day into plurality of numbers, and calculating the movement quantity in each unit time by repeating the operation, or the like; a liquid crystal indicator for graphing and displaying the movement quantity in each unit time in one day on a liquid crystal screen by an output signal from the control device; an operation key for performing time display and time correction; a scroll key for scrolling the liquid crystal screen; and a power supply battery.
