Patent ID: 8641172

Claim:
A liquid discharge head comprising: a first element substrate and a second element substrate, the first element substrate and the second element substrate including: a discharge port array in which a plurality of discharge ports that discharge liquid are disposed; a plurality of energy generating elements that generate energy for discharging liquid from the plurality of discharge ports; and a plurality of electric contacts electrically connected to the plurality of energy generating elements, the plurality of electric contacts including a plurality of first electric contacts disposed linearly along one end of the first element substrate and the second element substrate in a direction of arrangement in which the plurality of discharge ports are disposed, and a plurality of second electric contacts disposed linearly along the other end of the first element substrate and the second element substrate in the direction of arrangement, the first element substrate and the second element substrate being configured such that a distance between a center of gravity of the first electric contacts and a center of gravity of the discharge port provided at an end portion of the discharge port array on a side of the first electric contacts in the direction of arrangement is different from a distance between a center of gravity of the second electric contacts and a center of gravity of the discharge port provided at an end portion of the discharge port array on a side of the second electric contacts in the direction of arrangement, wherein the plurality of first electric contacts of the first element substrate and the plurality of second electric contacts of the second element substrate are disposed linearly, and the plurality of second electric contacts of the first element substrate and the plurality of first electric contacts of the second element substrate are disposed linearly.
