Abstract
An airfoil and a gas turbine including the airfoil. The airfoil includes a suction side and a pressure side having a cooling hole, a main cavity which is formed in an inner space formed by the suction side and the pressure side and into which a cooling fluid is introduced, an inner cooling flow path formed inside a wall body forming the pressure side and the suction side, and a collision jet hole formed in inner surfaces of the suction side and the pressure side and configured to perform colliding and cooling by introducing the cooling fluid into the inner cooling flow path, and a sub-cavity surrounding an inner cooling flow path outlet formed on an end portion of the inner cooling flow path, the sub-cavity being configured such that the inner cooling flow path outlet and a cooling hole inlet are in communication with each other.
