To provide a solid electrolyte sheet capable of increasing rigidity near an end surface of the solid electrolyte sheet, and a solid electrolyte secondary battery used with the solid electrolyte sheet.SOLUTION: A solid electrolyte sheet 10 includes a base 11 containing a solid electrolyte and formed in a plate shape, and a plate-shaped reinforcing part 12 formed on an outside of the base. The reinforcing part 12 is made of a combination of two electrical insulating members different in material, and is set to be higher in rigidity than the base 11. Since rigidity near the periphery of the solid electrolyte sheet can be increased, a risk of damage near the periphery of the solid electrolyte sheet can be reduced.SELECTED DRAWING: Figure 1 【課題】固体電解質シートの端面付近の剛性を高めることができる固体電解質シート、及びこの固体電解質シートと使用した固体電解質二次電池を提供する。【解決手段】固体電解質シート１０が、固体電解質を含み板状に形成された基部１１と、この基部の外側に形成された板状の補強部１２とから形成され、補強部１２は、材質が異なる２つの電気的絶縁部材を組み合わせて形成され、しかも基部１１に対して剛性が大きく設定されている。固体電解質シートの周縁部付近の剛性を高めることができるので、固体電解質シートの周縁部付近が損傷する恐れを少なくすることができる。【選択図】図１
