摘要：
Provided is an optical scanning device capable of solving the problem of low driving efficiency. A pair of coupling parts 12 join both ends of movable mirror part 11 having a reflective plane that reflects light to respective supporting parts 13. Each coupling part 12 has magnet part 21 having a permanent magnet, first spring part 22 that couples magnet part 21 to supporting part 13 in an oscillatable manner, and a second spring part that couples movable mirror part 11 to magnet part 21 in an oscillatable manner. Driver 14 generates magnetic fields acting on magnet part 21 to oscillate magnetic part 21 and thereby oscillate movable mirror part 11.
