To increase the reliability of an optical deflection element by increasing the resistance to moisture of a reflection unit.SOLUTION: The present invention includes: a reflection unit; a base body for supporting the reflection unit; a deformation unit surrounding the outer periphery of the reflection unit in a region outside a region in which the reflection unit of the base body is formed, the deformation unit protruding from or being recessed from a surface in which the reflection unit is formed; and a protection unit for covering the reflection unit and the deformation unit and protecting the reflection unit.SELECTED DRAWING: Figure 5

    【課題】反射部の防湿性を高めることで、光偏向素子の信頼性を向上させる。【解決手段】反射部と、前記反射部を支持する基体と、前記基体の前記反射部が設けられた領域の外側の領域において前記反射部の外周を囲むように配置され、前記反射部が設けられた面から突出または陥没の少なくとも何れか一方の形状に形成される変形部と、前記反射部と前記変形部とを覆い、前記反射部を保護する保護部と、を備える。【選択図】図5
