Abstract
A particle size D50 of the particle is not less than 50 nm and not more than 450 nm, or not less than 750 nm and not more than 10,000 nm. A refractive index of the particle is not less than 1.3 and less than 2.4. One of a mass ratio between the particles and the matrix polymer compound (particles/matrix polymer compound) and a mass ratio between the particles and the electrolyte salt (particles/electrolyte salt) is not less than 15/85 and not more than 90/10.
