A LIQUID EJECTION HEAD AND A METHOD OF MEASURING ELECTRICAL RESISTANCE IN A LIQUID EJECTION HEAD

A liquid ejection head includes actuators spaced along a first direction between a first edge and a second edge of a substrate in a second direction. Individual wirings are connected to a first terminal of an actuator and has a terminal portion at the first edge of the substrate. A common wiring has...

Zusammenfassung:	A liquid ejection head includes actuators spaced along a first direction between a first edge and a second edge of a substrate in a second direction. Individual wirings are connected to a first terminal of an actuator and has a terminal portion at the first edge of the substrate. A common wiring has a first portion and a plurality of second portions. Each second portion is branched from the first portion in the second direction and individually connects to a second terminal of an actuator. The first portion extends along the first direction on the substrate and has a first end terminal and a second end terminal spaced from each other. A monitor terminal is at a position between the first and second end terminals. The monitor terminal extends in the second direction from the first edge of the substrate toward the first portion to which it is electrically connected.
