We give an explicit quantum super field construction of the N = 2 super-Casimir WA(n) algebras, which is obtained from supersymmetric Miura transformation for the Lie super-algebra A(n,n-1). And also we give an extension of this algebras including a super-vertex operator which depends on simple root system of A(n,n-1).
