PROBLEM TO BE SOLVED: To provide an optical device, an optical scanner and an image display unit capable of two-dimensionally scanning light while suppressing warpage of a light reflection plate.SOLUTION: An optical scanner 1 comprises: a base part 111; a light reflection plate 113 fixed to the base part 111 and having a light reflection part with light reflectivity; a movable part 11 capable of oscillating around a Y-axis; a frame body part 13 arranged surrounding the base part 111 capable of oscillating around an X-axis orthogonal to the Y-axis; shaft parts 12a, 12b holding the movable part 11 while allowing oscillation around the Y-axis to the frame body part 13; and permanent magnets 21a, 21b arranged in the frame body part 13. The light reflection plate 113 is alienated from the shaft parts 12a, 12b in thickness direction, overlapping the shaft parts 12a, 12b in view of the thickness direction. The permanent magnets 21a, 21b are fixed to a surface on the light reflection plate 113 side of the frame body part 13. |
