Disclosed is a turbine blade including a turbine blade substrate including an iron-base alloy; an erosion shield plate including a Co-base alloy; and a shim including a Ni-Fe alloy, in which the erosion shield plate is fixed to a leading edge of the turbine blade substrate with the shim therebetween by an electron beam welding. Thus, a turbine blade having a highly reliable, bonded portion of an erosion shield, and a turbine rotor and a steam turbine using the turbine blade are provided. |
