  We discuss a natural way to generate the mu-term in supergravity scenario.
Once the supergravity effects are taken into account, the vacuum expectation
values (VEVs) of the heavy fields are in general shifted from the values in the
supersymmetric limit. We note that this fact is independent of any Kahler
ansatz and the values of the VEV shifts are of the order of the gravitino mass.
As an example, an explicit model is presented, in which both of the mu-term and
the B-term of the electroweak scale are generated by the VEV shifts through the
supergravity effects. This model is a kind of the next to minimal
supersymmetric standard model, but there is no light standard model singlet
field. Also, we emphasize that our discussion can be naturally applied to the
supersymmetric grand unified theory.
