A structure for cooling a turbine airfoil includes: a cooling passage formed between first and second airfoil walls; a lattice structure body formed by stacking a plurality of ribs so as to form a lattice pattern; a cooling medium discharge port provided at a downstream end portion of the cooling passage for discharging cooling medium to the outside; an exposed wall portion formed as a portion of the second airfoil wall extending beyond the cooling medium discharge port to the outside; and a flat surface portion formed in the cooling passage from an outlet of the lattice structure body to the cooling medium discharge port and at which the wall surfaces of the first and second airfoil walls are formed as flat surfaces.
