Abstract: An object of the invention is to provide a technology for further improving scanning performance. Provided is an optical scanning device including: a scanning unit including an optical waveguide configured to guide incident light and emit the light from an emission end, and a vibration unit configured to generate a vibration and vibrate the emission end; and a signal transmission unit configured to transmit a signal to the scanning unit and cause the scanning unit to scan an object, characterized in that the scanning unit includes a first bonding and vibration attenuating unit configured to bond, with an elastic member, an end surface of the vibration unit closer to the emission end and the optical waveguide.
