Abstract:
A liquid discharging head comprising:a discharging port for discharging liquid; a liquid flow path communicating with said discharging port; a bubble generating region in said liquid flow path for causing liquid to generate a bubble to be utilized to discharge liquid from said discharging port; a movable member having provided thereon a fulcrum and a movable portion disposed facing said bubble generating region, a free end of said movable portion being toward said discharging port and downstream of said fulcrum; liquid flow path side walls extending along sides of said bubble generating region such that, at any given point along said liquid flow path in a horizontal direction, said liquid flow path walls extend to a vertical extent at least equal to the vertical range of movement of said free end of said movable portion when said movable portion moves from a non-displacement state to a maximum displacement state; and a common communicating space for commonly communicating said liquid flow path with a neighboring liquid flow path, a portion of said common communicating space being positioned downstream of said fulcrum, wherein said bubble generating region is on one side of said movable portion of said movable member and said common communicating space is on an opposite side of said movable portion of said movable member.
