An electrochromic element, comprising:
- a first substrate;
- a second substrate disposed on the first substrate;
- and
- an electrochromic part disposed between the first substrate and the second substrate,
- wherein a change in light transmittance measured by Measurement Method below is less than 0.25:
- [Measurement Method]
- The electrochromic part is irradiated with similar sunlight at an intensity of 1000 W/m2 for 10 minutes through the first substrate, a first light transmittance of the electrochromic element before irradiation with the similar sunlight is measured, a second light transmittance of the electrochromic element after irradiation with the similar sunlight is measured, and the change in light transmittance is obtained by dividing a difference between the first light transmittance and the second light transmittance by the first light transmittance.
