Abstract
The present invention discloses a recording head and a method of manufacturing the recording head including an electrothermal transducer element for causing ink to be discharged through a discharge port by causing heat energy to act on the ink, a heat acting portion for causing the heat energy generated by the electrothermal transducer element to act on the ink present in an ink passage; and a substrate, either side of which has the electrothermal transducer element, and a residual side of which has the ink passage, so that the reliability is improved, an image is precisely recorded at high speed and an excellent manufacturing yield is realized.
