In a liquid lens containing electrode and an insulating first liquid and a conductive second liquid having non-miscibility and different refractive indexes, and optical characteristics are changed by a change of interface shape of the first and the second liquid by applying a voltage to the electrode: in a surface contact with an edge of interface of the first and the second liquids, a first region having an affinity for the first liquid and a second region having an affinity different from that of the first liquid are formed on the insulating layer, and when the interface shape of the first liquid and the second liquid is changed, by an affinity force to hold the first liquid within the first region and a force to move the edge to the second region by electro-wetting, the edge can be stably held at an edge of the first region.
