In addition, a wiring layer and a print element which are formed on the second interlayer insulation film formed on the first interlayer insulation film are connected by a second conductive plug which penetrates through the first and second interlayer insulation films. By manufacturing the element substrate by this arrangement, the thickness of an interlayer insulation film between a print element and a temperature detection element can be made thin, and the sensitivity of the temperature detection element can be improved.

摘要： According to an embodiment, a printing apparatus for printing an image on a print medium by a printhead while relatively scanning the printhead, and discharging ink from the printhead to the print medium is controlled as follows. That is, a time corresponding to a print resolution in a scanning direction of the printhead is divided into a plurality of times, and these print elements are time-divisionally driven by using the divided times as driving timings. At this time, it is controlled to form a plurality of groups each including a predetermined number of adjacent print elements of the print elements, and change the driving timings for each of the groups using the divided time as a unit.

摘要： A print head includes upper protective members located at positions corresponding to heat generating resistor elements to protect the heat generating resistor elements, and further, a part of the protective member can be eluted into ink when a current flows inside in a state in which the ink is stored in the pressure chambers. The print head includes a drive element and a logic circuit capable of allowing a current to independently flow in each of the upper protective layers so as to elute a part of the upper protective layer, in which the current flows, into the ink.
