LIQUID EJECTION RECORDING HEAD AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid ejection recording head having a good printing characteristic whereby an ejection nozzle can be processed by emission of a laser light without generating debris stuck to an ink ejection face and burr on an edge section of the ejection nozzle. SOLUTION: There is disclosed a liquid ejection recording head comprised of a top plate 10 having an ejection nozzle plate 1. An elastic body 4 made of silicon rubber is pressed against the ejection nozzle plate 1 along the shape thereof at a portion where an ejection nozzle 2 is to be formed. An excimer- laser light L is emitted thereto from a side opposite the face to which the elastic body 4 is pressed so that the ejection nozzle 2 for ejecting a liquid such as an ink is formed. As a result, it is possible to prevent debris 3 from being stuck to an ink ejection face 1a and to decompose to remove a cover part of the ejection nozzle 2 so that burr is not generated on an edge section of the ejection nozzle 2.
