Abstract
A recording element substrate includes a signal supply circuit and a common line which connects the signal supply circuit to first logic circuit array for a recording element and a second logic circuit array for a memory element in common. Furthermore, the first and second logic circuit arrays extend along a direction in which the common line extends, the first logic circuit array is disposed on one side of the common line, the second logic circuit array is disposed on the other side of the common line, and the first and second logic circuit arrays are arranged so that at least a portion of the first logic circuit array and a portion of the second logic circuit array overlap with each other in a direction orthogonal to the extending direction.
