We construct BRST invariant solitonic states in the OSp invariant stringfield theory for closed bosonic strings. Our construction is a generalizationof the one given in the noncritical case. These states are made by using theboundary states for D-branes, and can be regarded as states in which D-branesor ghost D-branes are excited. We calculate the vacuum amplitude in thepresence of solitons perturbatively and show that the cylinder amplitude forthe D-brane is reproduced. The results imply that these are states with evennumber of D-branes or ghost D-branes.Comment: 36 pages, 3 figures, LaTeX; typos correcte
