Abstract
This steam turbine blade is provided with: a blade body () extending in a radial direction and having an airfoil profile in a cross section perpendicular to the radial direction; and a heater (H) including a heating wire disposed so as to extend along a trailing edge (Er) of the airfoil profile in the blade body (). This configuration makes it possible to further mitigate an efficiency drop due to moisture attached to the surface of the steam turbine blade ().
