Provided is a character string retrieval device that reliably makes an operator aware that a character string that has been retrieved has been displayed in a display unit as a result of retrieving the character string from a search target such as text. The character string retrieval device (1), which retrieves character strings from a search target, is provided with: a display unit (20) that displays character string retrieval results; an operation unit (30) that detects operation input; a tactile feedback unit (40) that causes the operation unit (30) to vibrate; and a control unit (10) that provides control in such a manner that the range in which character string retrieval results are displayed on the display unit (20) is changed on the basis of the operation input detected by the operation unit (30). The control unit (10) is characterized in that the tactile feedback unit (40) is controlled in such a manner that tactile feedback is provided to a pressing object that is pressing the operation unit (30) when a retrieved character string is displayed on the display unit.
