An input pen () of the present invention is an input pen used for performing an input to a touch-panel-integrated liquid crystal display device () (display device). The liquid crystal display device () includes a plurality of photosensitive elements () that senses light transmitted through a panel surface. The photosensitive elements () detect a position of input by sensing an image on a surface of a display panel. The input pen () includes a retroreflective element () at its tip that is to be in contact with the display panel. The retroreflective element () is made up of a spherical glass () (spherical transparent member) and an elastic reflective element (). In this way, it is possible to provide an input pen which is to be used with a touch-panel-integrated display device and which makes it possible to perform a more accurate position detection.
