PURPOSE: A non-charging portable phone terminal is provided to supply power in real time using the electric wave transferred to a mobile communication terminal. CONSTITUTION: A non-charging portable phone terminal is composed of an electric wave receiving part(50), an electric wave-to-electricity conversion part(70), a booster(80), a main power nickel-cadmium battery(81), an auxiliary nickel-cadmium battery(82), a crystal oscillator(60), and an ATX chip(90). The non-charging portable phone terminal, receiving a signal through the receiving part(50) from a base station or a satellite, detects a voice signal by the potential difference between a ground signal and a data signal among the received signal. Succeedingly, the main power nickel-cadmium battery(81) drives the electric wave-to-electricity conversion part(70). The voltage generated as the electric wave-to-electricity conversion part(70) is driven is converted into an effective power by the booster(80). Then the effective power is stored in the auxiliary nickel-cadmium battery(82). The non-charging portable phone terminal is operated by this auxiliary nickel-cadmium battery(82).
