Abstract
A liquid ejecting head includes: a nozzle row configured by arranging nozzles ejecting a liquid in a first-direction in a second-direction orthogonal to the first-direction; a drive element; and stacked components defining a common liquid chamber communicating with the nozzle row, in which the stacked components include a filter partitioning the common liquid chamber into an upstream common liquid chamber and a downstream common liquid chamber, a first-case defining a first-common-liquid-chamber-portion as a part of the upstream common liquid chamber and stacked on the filter, and a second-case defining a second-common-liquid-chamber-portion as a part of the upstream common liquid chamber and stacked on the first-case, the second-common liquid-chamber-portion is positioned in a direction opposite to the first-direction from the drive element, and a width of the second-common-liquid-chamber-portion in a third-direction orthogonal to the first-direction and the second-direction is longer than a width of the first-common-liquid-chamber-portion in the third-direction.
