According to the embodiment of the present invention, a guide vane of a water turbine rotatable about an axis, including a guide vane for directing supplied flowing water toward the downstream side. The guide vane has a downstream end edge having an upper end portion and a lower end portion. The lower end portion of the downstream end edge is displaced in the direction orthogonal to an axis with respect to the upper end portion of the downstream end edge when viewed from the downstream side.
