Nozzle for liquid injection device and method of producing the same

Abstract

A nozzle for a liquid injection device, wherein a ceramic green sheet (11) used as a bottom part of a liquid injection device having a nozzle (12) disposed between a die (2) and a stripper (3) storing a punch (4) and the punch (4) is moved to form a hole part constituting the nozzle (12), the green sheet (11) is disposed between a die (2′) having a cavity wherein the outer shape of a projected part (12a) of the nozzle (12) is reversed and a stripper (3′) storing a punch (5) so that it is positioned in the direction opposite to that in the previous disposition and the punch (5) is moved to obtain the outer shape of the nozzle (12), and the green sheet (11) is baked, whereby, even in a drying device to which air is constantly applied vertically to the delivery direction of liquid, no injected liquid is deposited substantially at the tip part of the nozzle (12).
