There is provided an electric lens including a first lens and a second lens adjacent to each other, and a variable-refractive-index body that is held between a lens face of the first lens and a lens face of the second lens mutually having the same curved surface, and changes refractive index according to an externally applied electrical signal. A thickness of the variable-refractive-index body is uniform in at least a portion that transmits a light ray contributing to image formation.
