The present invention relates to a layered ZnSb, a ZnSb nanosheet, and a method for manufacturing the same. According to the present invention, a ZnSb nanosheet can be formed by efficiently peeling ZnSb, which is a polymorphic layered material having a structure different from that of a conventional 3D ZnSb. The high quality layered ZnSb nanosheet manufactured by the process can be mass-produced and can be applied to thermoelectric materials and the like. According to the present invention, a layered ZnSb structure can be manufactured by inserting and removing Na in the ZnSb 3D structure, and the newly manufactured layered structure can be easily peeled off.
