Abstract
The airfoil member of the present invention is provided with an airfoil body, an end wall which is installed at an end part of the airfoil body, a fillet portion which smoothly connects the end part of the airfoil body with the end wall, and a cooling channel which allows a cooling medium to circulate inside the airfoil body and the end wall and in which two main channels are connected so as to bend in a folding manner at a return channel. The return channel is formed so as to run along the fillet portion on a cross section intersecting with a center line of a profile of the airfoil body and also formed in such a manner that the width thereof in the profile thickness direction is greater than the width of the main channel in the profile thickness direction.
