PROBLEM TO BE SOLVED: To provide a gas turbine which efficiently inhibits a cooling hole from being closed by dirt entering into a blade.SOLUTION: The invention includes: blade bodies having airfoil shapes, each of the blade bodies having a cooling passage formed therein and in which cooling air flows from an air inflow port 14a to a cooling hole; and a casing 7 to which the blade bodies are attached, the casing 7 having a supply passage for supplying the cooling air supplied from an air supply port 7a to the air inflow port 14a of the cooling passage. The invention further includes a dirt receiving part 17 disposed at the air supply port 7a of the supply passage and including air release holes 17a, which open at the upstream side and circulate the cooling air flowing thereinto to the downstream side, and a storage part 17b which stores dirt at a bottom part. |
