PROBLEM TO BE SOLVED: To provide a steam turbine in which the pressure (static pressure) of a turbine exhaust is more highly recovered and the turbine exhaust performance is improved when the turbine exhaust in which the expansion work is ended is exhausted from a turbine exhaust chamber into a condenser. SOLUTION: The steam turbine is divided into an upper half steam guide 27a and a lower half steam guide 27b at the cross center of a steam guide 27. The divided upper half steam guide 27a is expanded from an upper half steam guide inlet edge line 40a toward an upper half steam guide outlet edge line 41a, while the divided lower steam guide 27b is expanded from a lower half steam guide inlet edge line 40b toward a lower half steam guide outlet edge line 41b. The lower half steam guide edge line 41b is shaped to connect an inclined outlet edge line 42 expanded from the cross center toward the bottom side, and a bottom outlet edge line 43 with a curved outlet edge line 44.
