PURPOSE: A turbine blade is provided to secure efficient cooling by improving the turbine blade. CONSTITUTION: A turbine blade(20) includes a platform(26) and an airfoil(22). The airfoil has a root(24) of the platform, a tip(28), a front edge(40) and a trailing edge(42), and an inner cooling passage network. The inner cooling passage network includes at least one trailing edge cavity, plural trailing edge holes(50) extended from the trailing edge to the trailing edge cavity, and plural tip holes extended from the tip to the trailing edge cavity.
