Provided is a simulator device allowing simplification and cost minimization. A simulator device that generates and emits, to a LiDAR shining a laser light at a plurality of scanning locations, a false light corresponding to said laser light, and comprises: a light focusing unit that focuses the laser light shined at the plurality of scanning locations; and a simulator that, in accordance with the laser light focused by the light focusing unit, generates the false light resembling scattered light that is produced in a prescribed location, and emits the false light to the LiDAR via the light focusing unit.
