Query: Fate of Inhomogeneity in Schwarzschild-deSitter Space-time   We investigate the global structure of the space time with a spherically
symmetric inhomogeneity using a metric junction, and classify all possible
types. We found that a motion with a negative gravitational mass is possible
although the energy condition of the matter is not violated. Using the result,
formation of black hole and worm hole during the inflationary era is discussed.
