Abstract
An optical element has a transmission spectrum characterized in that a local maximum falls within a wavelength region longer than 315 nm but shorter than or equal to 400 nm, a local minimum falls within a wavelength region longer than or equal to 380 nm but shorter than or equal to 500 nm, and the wavelength at the local maximum is shorter than the wavelength at the local minimum.
