Abstract
The present invention relates to an ink jet recording head and a production method therefor, wherein ink is spouted by vibrating a vibrating plate that is a wall part of a pressure chamber, using an ink jet energy generating part. In the ink jet recording head that comprises a main body formed by a plurality of pressure chambers provided corresponding to nozzles that spout ink, the vibrating plate that constitutes a wall of the compression chamber being provided to the main body and an energy generating part provided on the vibrating plate at a position corresponding to a forming position of the pressure chamber, which makes the ink inside the pressure chambers spouted from the nozzles by deformative-energizing the vibrating plate, the vibrating plate and the ink jet energy generating part are formed using the thin film forming technology.
