Abstract: The invention is directed towards an equipment operation state measurer having a power data acquirer and an operation state determiner. The power date acquirer acquires power consumption of equipment changing according to an operation state of the equipment. Additionally, a cause inputter accepts an input of a stop cause of the equipment from an operator, with respect to a stopped state determined by the operation state determiner, and sets the stop cause of the stopped state based on the input. Also, a computing unit obtains electric energy consumption for each stop cause, by integrating a period during which the stopped state corresponding to the stop cause continues and the power consumption in the period during which the stopped state continues, and is capable of measuring duration of the stopped state and the electric energy consumption for each stop cause of the equipment.
