Abstract: Curvature tensors of Kaehler type (or type *K*) are defined on a hermitian vector space and it has been proved that the real vector space of curvature tensors of type *K* on *V* is isomorphic with the vector space of sym metric endomorphisms of the symmetric product of , where (Theorem 3.6). Then it is shown that admits a natural orthogonal decomposition (Theorem 5.1) and hence every is expressed as . These components are explicitly determined and then it is observed that is a certain formal tensor introduced by Bochner. We call the *Bochner-Weyl* part of *L* and the space of all these is called the *Weyl subspace* of .
