摘要： According to an embodiment, a light deflecting element includes a dielectric body, a first electrode, and a second electrode. The second electrode is configured to sandwich the dielectric body with the first electrode so as to apply a voltage to the dielectric body. The second electrode includes orthogonal portions that are substantially orthogonal to an incident direction of a light beam passing through the dielectric body, parallel portions that are substantially parallel to the incident direction of the light beam. The orthogonal portions and the parallel portions are formed in an alternate manner on the light beam incident side of the dielectric body. The second electrode includes a linear sloping portion that slopes in a direction toward intersection with the incident direction of the light beam. The orthogonal portions, the parallel portions, and the linear sloping portion are formed integrally.
