The stereoscopic endoscope is provided with an R image pickup section and an R output section which are provided on a right side of an endoscope body, an L image pickup section and an L output section which are provided on a left side of the endoscope body, and an R memory and an L memory which store correction information for either right or left and identification information. The right and left image pickup sections and the right and left memories are correctly or incorrectly combined and are connected to the right and left output sections. The identification information combining section performs image combination of an image and identification information inputted from the R output section or an image and identification information inputted from the L output section and outputs a combined image.
