A variable focus prism has a first transmissive solution body, a second transmissive solution body that has a different refractive index to that of the first transmissive solution body, and a reflective solution body. The variable focus prism varies the shape of the transmissive surface and the reflective surface by electrical control of the transmissive surface formed on the interface between the first transmissive solution body and the second transmissive solution body, and the reflective surface formed on the interface between the second transmissive solution body and the reflective solution body.
