Abstract
A detectable indication member for an optical position detection device includes a round bar shaped shaft and a spherical body provided at the distal end of the shaft. The outer peripheral surface of the spherical body and the outer peripheral surface of an end portion of the shaft portion connected to the spherical body form a retroreflective portion. A portion of the shaft adjacent the base end of the end portion absorbs infrared light.
