A solid electrolyte (10) according to the present disclosure is provided with: a porous silica (11) having a plurality of holes (12) connected to one another; and an electrolyte (13) covering the inner surfaces of the plurality of holes (12). The electrolyte (13) includes: a 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide denoted by EMI-FSI; and a lithium salt dissolved in the EMI-FSI. The molar ratio of the EMI-FSI to the porous silica (11) is greater than 1.0 and less than 3.5. La présente invention concerne un électrolyte solide (10) comprenant : une silice poreuse (11) comportant une pluralité de trous (12) reliés les uns aux autres ; et un électrolyte (13) recouvrant les surfaces internes de la pluralité de trous (12). L'électrolyte (13) comprend : un 1-éthyl-3-méthylimidazolium bis(fluorosulfonyl)imide désigné par EMI-FSI ; et un sel de lithium dissous dans l'EMI-FSI. Le rapport molaire de l'EMI-FSI à la silice poreuse (11) est supérieur à 1,0 et inférieur à 3,5. 本開示の固体電解質（１０）は、相互接続された複数の孔（１２）を有する多孔質シリカ（１１）と、複数の孔（１２）の内表面を覆う電解質（１３）とを備えている。電解質（１３）は、ＥＭＩ－ＦＳＩで表される１－エチル－３－メチルイミダゾリウムビス（フルオロスルホニル）イミドと、ＥＭＩ－ＦＳＩに溶解したリチウム塩と、を含む。多孔質シリカ（１１）に対するＥＭＩ－ＦＳＩのモル比が、１．０より大きく、かつ、３．５未満である。
