PURPOSE: A turbine element airfoil is provided to minimize the shock loss by having a cooling passage network with a slot to be extended from a rear passage to a rear edge. CONSTITUTION: A cooling passage network contains a rear passage, a slot(182) and plural individual posts(130,132,134,136,138,140,142,146). The slot is extended from a rear passage toward a rear end. The slot separates a pressurizing and a sucking sidewalls of an airfoil partially and has a first and a second slot surfaces to be faced each other. The individual posts connect the slot between the pressurizing sidewall and the sucking sidewall.
