A scanning endoscope device including two core portions that are provided parallel to each other and that radiate illuminating beams having optical characteristics different from each other toward a subject； a driving unit that two-dimensionally scans the two illuminating beams radiated from the core portions by causing vibration of distal-end portions of the core portions； a light receiving unit that receives return beams, returned from the subject, of the two illuminating beams； a light splitting unit that splits the return beams received by the light receiving unit according to the optical characteristics； two light detecting units that photoelectrically convert the two return beams split by the light splitting unit to output captured image signals； and an image generating unit that generates two images for two viewpoint based on the each captured image signal.
