PROBLEM TO BE SOLVED: To provide a variable focus lens that allows an easy manufacturing process so as to prevent formation of bubbles. SOLUTION: The variable focus lens includes a fluid chamber containing first and second fluids which are immiscible and have different refractive indices, the fluid chamber, having a plurality of protrusions formed along a circumference of one open end thereof. The variable focus lens also includes a transparent plate, attached to the open end of the chamber via a sealing with a predetermined interval from the protrusions. The variable focus lens further includes a first electrode, disposed inside the chamber to act on the first fluid and a second electrode, disposed inside the chamber and is insulated from the first fluid.
