PURPOSE: A power monitoring apparatus having a standby power saving function, an electric load device, and a power monitoring method are provided to cut off or reduce standby power consumed in the power monitoring apparatus in a standby power mode of the electric load device. CONSTITUTION: A power monitoring apparatus(100) having a standby power saving function comprises a power metering module(110), a communication module(130), and a charging module(150). When a switch is on, the power metering module is powered. The power metering module checks the power consumption state of an electric load device and transmits the checked results to the communication module. The communication module transmits the received power consumption results to the outside and waits a call signal. When the communication module receives the call signal, the communication module turns on the switch. The charging module starts charging when the switch is on and supplies standby power to the communication module when the switch is off.
