Abstract:
A printhead comprises: a print element substrate that includes a print element; and a circuit board electrically connected to the print element substrate, wherein an ink leakage detection unit including a first electrode and a second electrode, and configured to detect an ink leakage is provided on the circuit board, and at least one of the first electrode and the second electrode is electrically connected to a terminal of the print element substrate.

Claim (Index 18):
A printing apparatus comprising:\n a printhead; and a control board electrically connected to the printhead, wherein the printhead includes a print element substrate that includes a detection unit configured to detect a state of a print element substrate, and a circuit board that includes an ink leakage detection unit configured to detect an ink leakage, and electrically connected to the print element substrate and the control board, the control board includes a control circuit and a power supply circuit configured to generate a power supply voltage applied to the printhead, and based on a change in output of the ink leakage detection unit and a change in output by the detection unit, the control circuit can control an output of the power supply circuit.
