Abstract
According to one embodiment, provided is an electrochromic device including an electrochromic layer, which contains a tungsten oxide material. The tungsten oxide material includes potassium-containing tungsten oxide particles having an average particle size of 100 nm or less. The potassium-containing tungsten oxide particles contain potassium within a range of 1 mol % to 50 mol %, and include a central section and a peripheral section adjacent to the central section. A periodicity of a crystal varies between the central section and the peripheral section.
