A liquid composition containing a solvent, an inorganic solid electrolyte, and a dispersant is provided. The dispersant is soluble in the solvent. A 10% volume fraction-component's particle diameter (D), a 50% volume fraction-component's particle diameter (D), a 90% volume fraction-component's particle diameter (D), and a mode diameter (D) of solids contained in the liquid composition satisfy D/D>10, D<1 μm, and D<2 μm, where D, D, D, and Dare measured by a laser diffraction method.

Liquid composition, storage container, and apparatus and method for producing solid electrolyte layer or electrode mixture layer

An electrochromic element including: a laminated body including a support formed of a resin, a first electrode layer, an electrochromic layer, and a second electrode layer, the support, the first electrode layer, the electrochromic layer, and the second electrode layer being disposed in the laminated body in this order; and a gel electrolyte disposed between the first electrode layer and the second electrode layer, wherein a phase separation temperature of the gel electrolyte is higher than a softening point of the support.
