<p>Provided is a solid electrolyte having a reduced amount of non-crosslinked monomers, capable of being cured rapidly to have good film-forming ability, and having high electroconductivity. The solid electrolyte is prepared by crosslinking a composition that consists essentially of a polymer compound, a solvent and an electrolytic salt through exposure to active radiations and/or under heat, in which the polymer compound has four functional polymer chains of formula (I): <CHEM> R<1> and R<2> each represent a hydrogen atom or a lower alkyl group, R<3> represents a hydrogen atom or a methyl group, m and n each represent 0 or an integer of 1 or more, and m + n≥35 in one polymer chain.</p> |
