A liquid lens is provided to control a focal distance thereof by forming a space between an ocular surface of a thin film and an object surface of the thin film, implanting a transparent liquid into the space, and adjusting the amount of transparent liquid. A rim(15) of an ocular surface of a thin film and a rime of an object surface of the thin film are attached to each other. A space(13) is secured between the ocular surface of the thin film and the object surface of the thin film. A liquid implantation hole(14) is formed at one side of the contacting rim between the ocular surface of the thin film and the object surface of the thin film in order to change a focal distance by supplying transparent liquid to the inside of the space. A center part(16) is thicker than the rim in order to change easily the focal distance according to the implanted amount of transparent liquid.
