Abstract
Provided is a lens optical unit, including at least one lens arranged at an object side of a solid-state image sensor. An imaging plane of the image sensor has a non-planar shape causing a sag amount in an optical axis direction to increase as a distance from an optical axis increases, and satisfies the expression: ρ×Sag>0, where ρ represents a Petzval curvature of an optical unit represented by ρ: rrepresents a curvature radius of a klens surface from the object side, nrepresents a refractive index of a medium before being incident to the klens surface from the object side, n'represents a refractive index of a medium after being emitted from the klens surface from the object side, and Sag represents a sag amount in the optical axis direction related to a given point other than the optical axis on the imaging plane.
