[Problem] To provide a scanning device with which the scanning area is widened by achieving both the efficiency of increasing the amplitude in non-resonant scanning and the efficiency of increasing the amplitude in resonant scanning in scanning using optical fiber vibration. [Solution] An optical scanning device comprises an optical fiber (3), a holding section (4) for holding said optical fiber (3) like a cantilever, a first drive device (10) provided on the tip side of said optical fiber (3), which vibrates said optical fiber (3) in a first direction, and a second drive device (20) provided between said holding section (4) for said optical fiber (3) and said first drive device (10), which vibrates said optical fiber (3) in a second direction that intersects with said first direction. |
