    Abstract: Provided are a novel optical element that can be used as a sensor or the like and a sensor including the same optical element. The optical element includes a cholesteric liquid crystal layer, in which the cholesteric liquid crystal layer has a liquid crystal alignment pattern in which a direction of an optical axis derived from a liquid crystal compound changes while continuously rotating in at least one in-plane direction, and in a case where a cross-section taken in a thickness direction conforming the in-plane direction in which the direction of the optical axis rotates is observed using a scanning electron microscope, a portion where a bright line and a dark line derived from the cholesteric liquid crystalline phase are discontinuous is provided in the cholesteric liquid crystal layer in the in-plane direction in which the direction of the optical axis rotates.
