Abstract
The present invention relates to a method for manufacturing an ink jet recording head having an ink path communicated with a discharge opening, a discharge energy generating element disposed in the ink path and a discharge opening plate on which the discharge opening is formed. The discharge opening plate is attached to an end surface of the ink path. The discharge opening is formed by irradiating an excimer laser light on the discharge opening plate from a side of the plate which is attached to the ink path.
