Claim:
1. A liquid discharge substrate, comprising: a plurality of discharge elements configured to receive a power source supplied from a common power source line; a plurality of driving elements configured to drive the plurality of discharge elements; a signal supplying unit configured to supply a control signal for controlling the plurality of driving elements; and a plurality of delay circuits disposed in a signal path which transmits the control signal, wherein the plurality of driving elements include first, second, and third driving elements, the plurality of delay circuits include first and second delay circuits, the first delay circuit delays a timing when the discharge element corresponding to the second driving element is driven relative to a timing when the discharge element corresponding to the first driving element is driven, the second delay circuit delays a timing when the discharge element corresponding to the third driving element is driven relative to the timing when the discharge element corresponding to the second driving element is driven, a delay amount of the first delay circuit is different from a delay amount of the second delay circuit, and delay amounts of more than two of the delay circuits arranged in series are sequentially increased or reduced.
