Abstract

　光学素子５０は、第１液体６２と、第１液体６２と異なる第２液体６３とを備えて容器５２内に封入し、当該容器５２内に印可する電圧を変化させることで、第１液体６２と第２液体６３との境界面形状（６４）を変化させることが可能な液体レンズ６１を有し、容器５２の内部を外部に対して断熱する断熱部材（真空層）が設けられている。上記光学素子において、好ましくは、前記第１液体および前記第２液体の一方は導電性を有し、他方は絶縁性を有する。上記光学素子において、好ましくは、前記物理量は電圧である。上記光学素子において、好ましくは、前記容器内において前記第１液体または前記第２液体と接する接触面の面積をＳＬとし、前記接触面のうち前記断熱部材を構成する部分の面積をＳＩとしたとき、式　ＳＩ／ＳＬ＞０．３０　の条件を満足する。
