PROBLEM TO BE SOLVED: To provide a two-dimensional scanning device capable of achieving cost reduction and a small size. SOLUTION: The two-dimensional scanning device 1 is equipped with: a swinging plate 43; a first swinging means causing the swinging plate 43 a first swing around a first axis T parallel to the plane including the swinging plate 43; a second swinging means causing the swinging plate 43 a second swing around a second axis U parallel to the plane including the swinging plate 43 and perpendicular to the first axis, at the same frequency and in a phase different by about 90°from the first swing; an amplitude varying means increasing or decreasing the amplitudes in the first and second swing with time; and a light source 2 emitting light to the swinging plate 43.
