Abstract
A liquid discharge head includes a first substrate in which a nozzle is formed, a second substrate disposed above the first substrate, an energy generation element that generates energy for discharging a liquid by a drive signal being applied, and a vibration plate that vibrates by the energy generated by the energy generation element and that is stacked on the second substrate, in which the vibration plate has a first area and a second area positioned at a position different from the first area and having a lower elastic modulus than an elastic modulus of the first area.
