We discuss a locally supersymmetric formulation for the boundaryFayet-Iliopoulos (FI) terms in 5-dimensional U(1) gauge theory on $S^1/Z_2$,using the four-form multiplier mechanism to introduce the necessary $Z_2$-oddFI coefficient. The physical consequence of the boundary FI terms is studiedwithin the full supergravity framework. For both models giving a flat and awarped spacetime geometry, the only meaningful deformation of vacuumconfiguration induced by the FI terms is a kink-type vacuum expectation valueof the vector multiplet scalar field which generate a 5D kink mass for chargedhypermultiplet. This result for the four-form induced boundary FI terms isconsistent with the one derived by the superfield formulation of 5D conformalsupergravity.Comment: 16 pages, no figures; conclusion changed for the warped cas
