Liquid discharge head substrate, liquid discharge head, and liquid discharge apparatus

A liquid discharge head substrate having a first side and a second side extending in a first direction, comprising:

• a discharge element array including a plurality of discharge elements arranged in the first direction and a supply port configured to supply liquid to the plurality of discharge elements;
• a driving element array including a plurality of driving elements corresponding to the plurality of discharge elements, arranged in the first direction, and configured to drive the discharge elements;
• a control circuit configured to control the driving element array;
• and
• a terminal region including a plurality of terminals arranged in the first direction along the first side and including a terminal configured to receive a power supply voltage to the liquid discharge head substrate,
• wherein at least one of the driving element array and the control circuit is arranged in a circuit region on a side opposite to the terminal region with respect to the discharge element array in a second direction crossing the first direction.
