The present invention is intended to provide a gel-type solid electrolyte having flexibility while maintaining the advantages of an ionic liquid by effectively internalizing the ionic liquid into a porous metal oxide. To this end, the present invention provides the gel-type solid electrolyte which includes an ionic liquid in a porous metal oxide prepared from a silane compound represented by the following Chemical Formula 1: n Si(R 1 ) x (OR 2 ) y (CR 3 ═CR 4 R 5 ) (4-x-y) [Chemical Formula 1]n in the Formula, R 1 and R 2 are alkyl groups with carbon numbers in the range of 1 to 3, which are independent from each other; R 3 , R 4 and R 5 are each independently hydrogen, a halogen element or an alkyl group having 1 to 5 carbon atoms; and x is an integer in the range of 0≦x≦3, y is an integer in the range of 1≦y≦4 and x+y is an integer in the range of 2≦x+y≦4. |
