A light emitting pointer device which can reduce luminance unevenness at a light emitting face is provided. An annular rib is provided between a first holding portion holding an emission shaft and a second holding portion holding a light entrance shaft and the annular rib thereby covers a corner of the light entrance shaft. As a result, the light is not likely to enter a pointer body from the corner of the light entrance shaft, thereby reducing stray light and reducing luminance unevenness. An upper face of the annular rib on the light entrance shaft side has a radius of curvature that is greater than a radius of curvature of the corner of the light entrance shaft and is tapered, thus the corner can be easily covered with a space between the light entrance shaft and the annular rib.
