Abstract:
A blade having a flow path forming plate (60o) that defines a portion of a combustion gas flow path.

The opening density of the multiple rear passages (75) in a middle region (MP) in the rear end surface (62b) is higher than the opening density of the multiple rear passages (75) in a dorsal region (NP) and/or a ventral region (PP) in the rear end surface (62b).
