| 1. A solid electrolyte, comprising:
an organic/inorganic composite material having pores with a mean diameter of 1 to 30 nm and a skeleton comprising
at least one structural unit expressed by the following Formula (1)
 wherein
R1 is an organic group with at least one carbon atom, and
M is a metal atom;
the carbons of R1 to which M is bonded may be the same or different;
R2 is a hydrogen atom, a hydroxyl group, or a hydrocarbon group;
x is an integer obtained by subtracting 1 from the valence of the metal M,
n is an integer greater than or equal to 1 and less than or equal to x, and
m is an integer greater than or equal to 1;
wherein said organic/inorganic composite material has at least one functional group having an ion exchange function said functional
group being bonded to an organic group inside the pores;
wherein at least 60% of a total pore volume of said organic/inorganic composite material is included in the range of +/−40%
of the mean pore diameter on the pore diameter distribution curve.
