To provide a mold for turbine blade capable of suppressing deformation in a precision molding occurring deformation due to the thermal stress, and to provide a method for manufacturing a turbine blade.
The mold for turbine blade for manufacturing a turbine blade having a leading edge, a trailing edge, a positive pressure surface which is curved in a recessed manner and a negative pressure surface which is projectingly curved, includes a mold body 8 having a blade-shaped space 2 having a shape of the turbine blade, and a heat insulating space 3 which is arranged with the predetermined spacing from the blade-shaped space 2 in the sectional view of the blade-shaped space 2, extends to an area 24 corresponding to the negative pressure surface from an area 23 corresponding to the positive pressure surface of the blade-shaped space 2 via a section 22 corresponding to the trailing edge, and also extends in the span direction of the turbine blade.
