Optical reflection element

An optical reflection element comprising:

• a supporting body;
• a first oscillator having a first end joined to the supporting body and having turn portions;
• a second oscillator having a first end joined to the supporting body and having turn portions;
• and
• a mirror portion having a reflection surface;
• wherein:
• the mirror portion is joined to a second end of the first oscillator, and is joined to a second end of the second oscillator;
• wherein the mirror portion has a mirror portion central axis passing through a center of the mirror portion along a direction where the first and second oscillators, and the mirror portion are arranged side-by-side;
• each of the first and second oscillators has a drive portion that oscillates the mirror portion;
• outer circumferences of the turn portions of the first and second oscillators are located outside a first end portion axis that is parallel to the mirror portion central axis, and passes a farthest portion from the mirror portion central axis in the mirror portion;
• and
• outer circumferences of the turn portions of the first and second oscillators are located outside a second end portion axis that is parallel to the mirror portion central axis, and passes a farthest portion from the mirror portion central axis in the mirror portion.

• each of the first and second oscillators has a drive portion that oscillates the minor portion:
• a first joining position of the mirror portion and the first oscillator is located on a side opposite to a side where a second joining position of the supporting body and the first oscillator is located with respect to the oscillation axis;
• and
• a third joining position of the mirror portion and the second oscillator is located on a side opposite to a side where a fourth joining position of the supporting body and the second oscillator is located with respect to the oscillation axis.
