1. An all-solid-state secondary battery comprising:
a positive electrode;
one or more solid electrolyte-containing layers; and
a negative electrode,
the one or more solid electrolyte-containing layers each including the following components (i) to (iii):
(i) an inorganic solid electrolyte;
(ii) a heat-resistant resin; and
(iii) at least one selected from the group consisting of an ionic liquid, a mixture of an ionic liquid and a lithium salt, and a polymer electrolyte, wherein
in each of the one or more solid electrolyte-containing layers, the components (i) to (iii) are uniformly distributed in a film thickness direction, and
when the one or more solid electrolyte-containing layers are a plurality of solid electrolyte-containing layers, two or more of the plurality of solid electrolyte-containing layers are not consecutively formed on top of each other.
