摘要:
A liquid ejecting head for ejecting a liquid by generation of a bubble, comprises a first liquid flow path in fluid communication with an ejection outlet, a second liquid flow path having a heat generating element for applying heat to the liquid to generate a bubble in said liquid, and a supply path for supplying the liquid to above said heat generating element from an upstream side of said heat generating element in a direction along said heat generating element, a movable member disposed as facing the heat generating element, displaced to a side of said first liquid flow path, based on a pressure generated when said heat generating element is driven, and having a free end, and a guide path for flowing the liquid above said heat generating element in said second liquid flow path.
