To provide a personal digital assistant equipped with a stereo camera, which contains: a stereo camera section having a lens and an imaging device in combination, one being left and the other right; a stereo finder/viewer section that has an eyepiece and a display device in combination, one being left and the other right; and a personal digital assistant section connected to a public communication line by radio.

Both sides of the personal digital assistant, which are comparatively less used, are paid attention in order to mount the stereo camera section 2 and the stereo finder/viewer section 3. The stereo camera section 2 has the lens and the imaging device used in combination, one being left and the other right, in the personal digital assistant that is small in device mounting space and mounting surface area. The finder/viewer section 3 has the eyepiece and the display device used in combination, one being left and the other right. Devices required as a stereo camera are disposed in these sides. Thus, the personal digital assistant equipped with the stereo camera is characterized by mounting a function as the stereo camera and a function as the a stereo finder/viewer without sacrificing the normal operation of the personal digital assistant.
