1. A composite membrane comprising
a conductive array comprising a plurality of ion conductive inorganic particles spaced apart from each other, wherein
a circumference and a width of a surface of each ion conductive inorganic particle included in the conductive array satisfies Inequality (1)
x≥3.2y, wherein x is a circumference and y is a width, and  Inequality (1)
 wherein a distance between a first ion conductive inorganic particle of the plurality of ion conductive inorganic particles and a second ion conductive inorganic particle, which is adjacent to the first ion conductive inorganic particle in a plan view, is 0% to about 20% of the width of the surface of the first ion conductive inorganic particle,
wherein the plurality of ion conductive inorganic particles comprises at least nine ion conductive inorganic particles, and
wherein the ion conductive inorganic particles are regularly, uniformly arranged; and
an organic material between the plurality of ion conductive inorganic particles.
