Abstract
An ink jet head includes an actuator, a driver IC, a first capacitor, a second capacitor, and a fuse. The actuator is configured to cause ink to be discharged from nozzles. The driver IC is configured to drive the actuator. The first capacitor is connected between a ground line and a first node of a power supply line connected to the driver IC. The second capacitor is connected between a ground line and a second node of the power supply line. A capacitance of the second capacitor is less than a capacitance of the first capacitor. The fuse is on the power supply line between the first node and the second node.
