Zusammenfassung:	According to an embodiment, a turbine stator blade (100) disposed in a working fluid flow path (15) in a casing (20) of a gas turbine (10), includes: a blade effective part (110) disposed in the working fluid flow path (15); an outer circumferential sidewall (120) having a plate-shaped part (123) that is connected to a radially outer end portion of the blade effective part (110), and hooks (121, 122) each extending radially outward and circumferentially from the plate-shaped part (123) and having a tip engaged with the casing (20); and an inner circumferential sidewall (130) connected to a radially inner end portion of the blade effective part (110). At least one slit (121s, 122s) is formed at the rear hook (121) or front hook (122) to divide the hook (121, 122) in a circumferential direction, and the hook (121, 122) has a seal member to seal the slit (121s, 122s).
