A liquid ejecting head and a liquid ejecting apparatus are designed so as to suppress the influence of noise on control signals. The liquid ejecting head has a plurality of terminals electrically connected with a contact point provided in the liquid ejecting apparatus, and a liquid ejecting element substrate having a liquid ejecting element formed for ejecting liquid in response to the control signals transmitted from the liquid ejecting apparatus. A power source terminal for drive and a ground terminal for drive, which are provided for driving the liquid ejecting element, are arranged adjacent to each other, and a power source wiring that connects the power source terminal for drive with the liquid ejecting element substrate and a ground wiring that connects the ground terminal for drive with the liquid ejecting element substrate are at least partially arranged in parallel.
