The quantum field theory in de Sitter ambient space provides us with a comprehensive description of massless gravitational fields. Using the gauge-covariant derivative in the de Sitter ambient space, the gauge invariant Lagrangian density has been found. In this paper, the equation of the conjugate spinor for massless spin-3/2 field is obtained using the Euler-Lagrange equation. Then the field equation is written in terms of the Casimir operator of the de Sitter group. Finally, the gauge invariant field equation is presented.
