To provide a method for forging a turbine blade that can enhance the material yield compared with a conventional one, reduce the man-hours for forging, have good forging, and effectively reduce die/mold costs required for forging the turbine blade.

Multiple moving blades 10 and 12 as turbine blades are forged in the longitudinal direction as one connecting body 26 and thereafter separated into each moving blade 10 or 12 to gain a single body of the moving blade 10 or 12.
