Abstract: A pressure regulating unit capable of suitably regulating pressure to be applied to liquid, a liquid supplying apparatus, and a liquid ejecting apparatus are provided. An ink communication path allows an ink introducing chamber communicating with an ink inlet and a pressure chamber communicating with an ink outlet to communicate with each other. A part of the pressure chamber is formed of a flexible film. A valve including a valve body and a valve seat adjusts an opening degree of the ink communication path. An urging member applies, to the valve, a first urging force acting in a direction in which the ink communication path is closed. An urging member applies, to the film, a second urging force that is greater than the first urging force and acts in a displacement direction in which the volume of the pressure chamber is reduced.

Abstract: A liquid ejection head includes an electrical wiring substrate and a printing element substrate, wherein the position variation of the printing element substrate due to curing of a sealing agent is eliminated. Specifically, a gap between two support members is covered with the electrical wiring substrate so as to be able to prevent a first sealing agent from flowing into this gap. As a result, even in the case where the size of the gap varies due to the variation in the dimensional accuracy and/or the variation in the assembly accuracy, the first sealing agent will not enter this gap, and therefore the shape thereof can be made substantially uniform regardless of the positions. This results in a substantially uniform stress in curing and contracting of the first sealing agent, and the variation in the mounting position of the printing element substrate can be suppressed.
