The portable telephone set includes an input key determining portion 13, a retrieval processing portion 14, and a display part 17. When key input occurs at a standby mode, the input key determining portion determines the type of the operated key. Whenever anyone of numerical keys is operated, the retrieval processing portion performs incremental retrieval of a character string corresponding to the operated numerical key, while all of the character data managed with each of the application are made as a subject to be searched. The display part displays the retrieval result whenever the incremental retrieval is performed. COPYRIGHT: (C)2010,JPO&INPIT
