Abstract:
A liquid discharge head may reduce possibility that pressure from a discharge unit reaches a third channel and a fourth channel. The liquid discharge head includes a plurality of discharge units each including a discharge hole, a pressurization chamber communicating with the discharge hole, a first channel for liquid supply to the pressurization chamber, and a second channel for liquid collection from the pressurization chamber, a pressurizing part configured to pressurize the pressurization chamber, a third channel connected commonly to the first channels of the plurality of discharge units, the third channel for liquid supply to the discharge units, a fourth channel connected commonly to the second channels of the plurality of discharge units, the fourth channel for liquid collection from the discharge units, and a fifth channel connecting the discharge units and having channel resistance larger than channel resistance of the first channel and the second channel.
