<P>PROBLEM TO BE SOLVED: To provide an optical scanner in which noise is reduced. Ž<P>SOLUTION: The optical scanner includes: a first oscillator 10 which has a light reflection substrate 11 having light reflectivity and a beam 13 which supports the light reflection plate 11; a sub oscillator 20 which has a movable substrate 21 and a beam 23 which supports the movable substrate 21; and magnets 14, 24 and coils 15, 25 which torsionally deform the beams of the first oscillator 10 and of the sub oscillator 20 to drive the oscillators around a driving axis X, wherein the beams 13, 23 are arranged along the driving axis X of the first oscillator 10, thus the first oscillator 10 and the sub oscillator 20 are arranged in series with respect to the driving axis X, the driving frequency of the sub oscillator 20 is the same as that of the first oscillator 10 and the phases are reversed.
