ABSTRACT:
An electrochromic element wherein, in a colored state of the electrochromic element, a first average optical density in a first wavelength range of 450 to 470 nm, a second average optical density in a second wavelength range of 540 to 560 nm and a third average optical density in a third wavelength range of 630 to 650 nm have a fluctuation (difference of a maximum value and a minimum value of the first to third average optical densities) equal to or less than 0.5.
