PROBLEM TO BE SOLVED: To provide a support structure of stator coil ends of a turbine generator that causes no deterioration in durability by heat accumulation and that can regulate the deterioration of rigidity of the stator coil ends after a long-time operation. SOLUTION: The turbine generator of this invention is equipped with a rotor for generating a rotating magnetic field and a stator provided at the outside periphery of this rotor. The stator comprises a slotted stator core which keeps stator coils arranged in the slots. The stator coils project axially from the stator core, have the stator coil ends that are rolled, and have an outside peripheral side cut-head conic shell-like member made of an insulation material formed on at least a part of the outside circumferential side of the stator coil ends.
