Disclosed are an optical element, an optical element array, and a method of manufacturing an optical element capable of forming a desired interface shape. In a microlens and a microlens array, at least one of a transparent liquid forming a liquid phase and microbubbles forming a gas phase is subjected to temperature adjustment by a curvature control part. The transparent liquid and the microbubbles subjected to temperature adjustment thermally expands or contracts, such that the shape of a curved interface formed between the transparent liquid and the microbubbles is changed.
