A vari-focal lens is provided to vary a focal distance of a lens by changing a curvature of elastic transmissive film through pressure change applied to liquid material. At least first operation hole(11) is formed on a first light-transmissive substrate(10), and a lens frame(30) is formed on a first light-transmissive substrate so that the first liquid chamber is formed. A second light-transmissive substrate(50) is formed on the lens frame so that the second liquid chamber(52) is formed. The light transmissive film blocks a lens pit of the lens frame while being installed on the lens frame.
