Abstract:
1. A liquid discharge head comprising: a first element substrate and a second element substrate, the first element substrate and the second element substrate including: 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.
