A semiconductor device for controlling discharge of a liquid includes a power supply terminal, a ground terminal, driving portions arranged along a straight line between the power supply terminal and the ground terminal to discharge a liquid, a power supply line extending along the straight line from the power supply terminal to supply a power supply voltage to the driving portions, and a ground line extending along the straight line from the ground terminal to supply a ground voltage to the driving portions. A width of the power supply line in a direction perpendicular to the straight line continuously or gradually decreases away from the power supply terminal, and a width of the ground line in the direction continuously or gradually decreases away from the ground terminal. |
