Abstract

Electrochromic device including: first electrode (12); a first auxiliary electrode (18); a second electrode (15); a second auxiliary electrode (19) having average distance of 100 mm or less with the first auxiliary electrode (18); an electrochromic layer (13); a solid electrolyte layer (14); and controlling unit configured to control to apply voltage according to a driving pattern that is at least one selected from the group consisting of a first driving pattern, a second driving pattern, and an initialization driving pattern, wherein the first driving pattern is a driving pattern configured to turn the electrochromic layer into first coloring state, the second driving pattern is a driving pattern configured to turn the first coloring state into a second coloring state that has coloring density lower than coloring density of the first coloring state, and the initialization driving pattern is driving pattern for forming an initial decolored state.
