Abstract
An ink jet recording apparatus having a recording head wherein an electrothermal converting element for generating the emission energy and a semiconductor functional element are integrally formed within a semiconductor substrate. The functional element with its base and collector shorted is electrically connected to the electrothermal converting element. Thereby, variation in ink emission is limited so that the recording head can record high quality images.
