Abstract:
An embodiment of this invention is directed to determining a discharge status of liquid discharged from a liquid discharge head capable of accurately determining the discharge status of each nozzle at high speed with a simple arrangement. According to the embodiment, a base includes an electrothermal transducer configured to supply heat to liquid, a first temperature detection element configured to detect the temperature of the electrothermal transducer, and a second temperature detection element configured to detect the temperature of the same electrothermal transducer. In this case, the first and the second temperature detection elements are arranged so that at least part of each of the first and second temperature detection elements is included immediately above or below a region where the electrothermal transducer is arranged in the base.
