• We analyze dilaton condensation in the covariantized light-cone closed string field theory. We show by explicit calculation that an infinitesimal condensation of the dilaton field gives rise to the shift of the string coupling constant g by an amount δg=-((d-2)/2)g, where d is the space-time dimension. This agrees with Yoneya's result obtained in the light-cone gauge string field theory. We also show that the direct effect of the dilaton condensation is interpreted as the Weyl-scaling of the full OSp(d-1,1∣2) metric including the ghost direction also.
