Zusammenfassung:	To provide an electrochromic element capable of forming distribution of light transmittance at the time of color development.SOLUTION: An electrochromic element 10 comprises a first substrate 11 and a second substrate 12 disposed to face each other, a first transparent electrode 13 formed on the front surface of the first substrate 11 on the side facing the second substrate 12, a second transparent electrode 14 formed on the front surface of the second substrate 12 on the side facing the first substrate 11, and a coloring layer 15 provided between the first transparent electrode 13 and the second transparent electrode 14. The coloring layer 15 includes electrochromic material and an electrolyte. A pattern of the electrochromic material or a concentration gradient is formed in at least a part of the coloring layer 15.SELECTED DRAWING: Figure 1 【課題】発色時に光透過率の分布を形成することが可能なエレクトロクロミック素子を提供する。【解決手段】エレクトロクロミック素子１０は、対向して設けられている第一基板１１及び第二基板１２と、第一基板１１の第二基板１２と対向する側の表面に形成されている第一透明電極１３と、第二基板１２の第一基板１１と対向する側の表面に形成されている第二透明電極１４と、第一透明電極１３と第二透明電極１４の間に設けられている発色層１５を有する。発色層１５は、エレクトロクロミック材料及び電解質を含む。発色層１５の少なくとも一部は、エレクトロクロミック材料のパターン又は濃度勾配が形成されている。【選択図】図１
