PROBLEM TO BE SOLVED: To improve the reliability of a gas turbine and its stationary blade without deteriorating the sealing ability against coolant and the life of the stationary blade even if installing a probe for monitoring the inside of a gas path in the gas turbine and its stationary blade. SOLUTION: A pipe-like projected section 6 formed on the front side inside of an outer peripheral side end wall section 2 is erected facing the outer peripheral side from a base section 2a, which is an internal bottom face, and the outer peripheral side tip penetrates and projects outside more than a cavity cover 11, and the periphery is welded and jointed. This constitution improves an allowable value for the stress caused by thermal deformation and eliminate the necessity of the welded part to a gas path wall 28 in structure, for improving durability against a high temperature main flowing gas 21.
