Abstract
An end plate of a blade has a gas path surface facing a combustion gas channel side, an end surface along an edge of the gas path surface, a plurality of channels, and a skirt hole. The plurality of channels extend along the direction of a partial end surface, which is a portion of the end surface, and are arranged in a perspective direction with respect to the partial end surface. The skirt hole opens at the partial end surface. The skirt hole communicates with an inside channel, which is the channel of the plurality of channels that is farthest from the partial end surface.
