A watt hour meter is provided to prevent a device of an operating part from being damaged by mounting a measuring part and an operating part on a printed circuit board separated with a sufficient distance from the high voltage. A measuring part(102) includes a detection unit to detect power consumption of a target system. The measuring part includes a transmission unit transmitting the data to show the detected power consumption by wireless. An operating part(116) includes a receiving unit to receive the data transmitted by wireless. The operating part includes an operating unit to process the received data to the data showing the electric energy consumed by the target system. An insulating unit insulates the measuring part and the operating part electrically. |
