  We study the general effects of anomalous U(1)_A gauge symmetry on soft
supersymmetry (SUSY) breaking terms in large volume scenario, where the MSSM
sector is localized on a small cycle whose volume is stabilized by the D-term
potential of the U(1)_A. Since it obtains SUSY breaking mass regardless of the
detailed form of K\"ahler potential, the U(1)_A vector superfield acts as a
messenger mediating the SUSY breaking in the moduli sector to the MSSM sector.
Then, through the loops of U(1)_A vector superfield, there arise soft masses of
the order of m_{3/2}^2/8\pi^2 for scalar mass squares, m_{3/2}/(8\pi^2)^2 for
gaugino masses, and m_{3/2}/8\pi^2 for A-paramteres. In addition, the massive
U(1)_A vector superfield can have non-zero F and D-components through the
moduli mixing in the K\"ahler potential, and this can result in larger soft
masses depending upon the details of the moduli mixing. For instance, in the
presence of one-loop induced moduli mixing between the visible sector modulus
and the large volume modulus, the U(1)_A D-term provides soft scalar mass
squares of the order of m_{3/2}^2. However, if the visible sector modulus is
mixed only with small cycle moduli, its effect on soft terms depends on how to
stabilize the small cycle moduli.
