An object of the present invention is to simplify and miniaturize the structure of a mirror moving part in a two-dimensional optical scanning mirror device, a two-dimensional optical scanning device and an image projection device. A two-dimensional optical scanning mirror apparatus of the present invention is a two-dimensional optical scanning mirror apparatus comprising a movable mirror portion (10) supported on a substrate so as to be two-dimensionally scannable, a hard magnetic thin film Wherein a ratio of a magnetic field generated by the magnetic field generating device to a coercive force of the hard magnetic thin film is set to 0.2 Or less.
