We complete the superfield description of generic 5D supergravity in N=1 superspace, which is based on the superconformal formulation. Especially we clarify the gravitational couplings to the bulk matters at linear order in the gravitational superfields. They consist of four N=1 superfields, two of which are physical degrees of freedom. This formulation provides a powerful tool to calculate quantum effects, keeping the N=1 off-shell structure.
