Abstract: A telephone directory address storing method and an information terminal by which telephone directory information is efficiently managed to achieve augmentation of the operability. The information terminal includes a display section, a storage section, an inputting section, a circuit interface section, and a control section for controlling the entire information terminal. The control section has a function of drawing a window delineated by closed line segments on the display section. The display section draws a first window displayed most forwardly with respect to any other window, fetches a character train selected on a second window into the first window through the storage section, waits a call origination instruction from the inputting section in the first window, dials in response to a call origination instruction from the inputting section through the circuit interface section, and simultaneously stores the character train selected on the second window into a telephone directory address storage section.
