CP T groups of higher spin fields are defined in the framework of automorphism groups of Clifford algebras associated with the complex representations of the proper orthochronous Lorentz group. Higher spin fields are understood as the fields on the Poincaré group which describe orientable (extended) objects. A general method for construction of CP T groups of the fields of any spin is given. CP T groups of the fields of spin-1/2, spin-1 and spin-3/2 are considered in detail. CP T groups of the fields of tensor type are discussed. It is shown that tensor fields correspond to particles of the same spin with different masses.
