Abstract:
A liquid discharging head comprising:an electrothermal converting element for generating thermal energy to be used for discharging a liquid from a discharge port and forming an effective bubbling region for generating a bubble; and a moveable member provided opposite to said electrothermal converting element and having a free end extending toward said discharge port, said moveable member also having a fulcrum located further from said discharge port than said free end, said moveable member dividing a liquid flow path above said electrothermal converting element into first and second liquid flow paths, said first liquid flow path being conductively connected to said discharge port and the second liquid flow path being provided with said electrothermal converting element, said free end of said moveable member being provided opposite to said electrothermal converting element on a downstream side of a center of said effective bubbling region with respect to a direction toward said discharge port and on an upstream side of the end of said effective bubbling region nearest said discharge port, and a heat generating surface of said electrothermal converting element being substantially flush with or smoothly continuous with an upstream surface adjacent said heat generating surface.
