Abstract:
1. A producing method of an electrostatic sucking type liquid jetting head having a plurality of nozzles for jetting liquid solution as a droplet from a nozzle edge, comprising: forming a plurality of jetting electrodes on a base plate for applying a jetting voltage; forming a photosensitive resin layer on the base plate so as to cover all of the plurality of jetting electrodes; making the photosensitive resin layer stand with respect to the base plate so as to correspond to each jetting electrode and so as to form the photosensitive resin layer in a nozzle shape having a nozzle diameter of more than 0.2 μm and of not more than 4 μm, by exposing and developing the photosensitive resin layer; forming an in-nozzle passage so as to establish a communication from an edge portion of the nozzle to the jetting electrode in the nozzle; and connecting the in-nozzle passage to a liquid solution supplying channel corresponding to the plurality of nozzles.
