PURPOSE: A method and apparatus for avoiding noise in a non-contact charging system are provided to prevent performance degradation and a malfunction by eliminating causes which have a negative effect by avoiding the noise which is generated in a wireless charger. CONSTITUTION: A wireless charge unit(110) is used as a module for supplying power to a charger circuit(130). The wireless charge unit provides a signal informing wireless telecommunication performance to a switch(120) while wirelessly communicating with an external wireless power transmission unit. A modem(150) provides the signal informing current wireless telecommunication performance to the switch when communicating with a current node on a different network. The switch isolates wireless charge power according to a wireless charge communication signal from the wireless charge unit and a modem communication signal from the modem. The charger circuit charges a battery(140) using the wireless charge power which is outputted from the switch.
