A novel optical scanning device which utilizes the light integrating technique is provided. In the device, a light beam is deflected by forming a light deflecting portion and a condensing thin film lens on a thin film waveguide path and further, the deflected light is transmitted by a transmission path bundle wider in the light exit portion thereof than in the light entrance portion thereof. The device is a compact optical scanning device which can scan a wider area at high speed.
