Patent ID: 7192122

Claim:
A liquid ejecting head which causes electrostatic force to act on a solution containing charged particles such that droplets of said solution are forced out through a two-dimensional array of ejecting portions, comprising: a first insulating substrate having ejecting orifices opened in positions corresponding to the layout of said ejecting portions such that said solution is forced out through said ejecting orifices; a second insulating substrate that is provided a specified distance from the first substrate so as to form a space between said first substrate and the second substrate which constitutes a flow channel for said solution; electrodes for controlling the ejection of said solution which are provided on the surface of said first substrate which is remote from said second substrate in such positions that each electrode surrounds the periphery of the associated ejecting orifice; a wall that is erected in said space to partition said flow channel in said space into an inflow region and an outflow region, said wall running in a serpentine path through said space to traverse said space in a direction perpendicular to the direction of the flow of said solution, and said wall passing by the positions of the ejecting orifices provided in said first substrate; and projecting solution guides that are erected on a ridge portion of said wall in positions corresponding to the positions of the ejecting orifices provided in said first substrate, said solution guides extending through said ejecting orifices to protrude from the surface of said first substrate which is remote from said second substrate; and wherein the solution flowing through said space passes through said ejecting orifices to be supplied to said solution guides.
