  Several physical quantities of light hadrons are examined by a new
holographic model of QCD, which is the modified version of the one proposed by
Erlich et al. defined on AdS${}_5$. In our model, AdS${}_5$ is deformed by a
non-trivial bulk scalar, this is corresponding to adding the mass term of the
adjoint fermions to the 4d SYM theory dual to the gravity on AdS${}_5$. We find
that this deformation should be taken to be rather small, but its important
effects are also seen.
