Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a nozzle row configured by arranging nozzles, configured to eject a liquid in a first direction, in a second direction orthogonal to the first direction;
• a drive element for ejecting the liquid from the nozzles of the nozzle row;
• and
• stacked components defining a common liquid chamber communicating with the nozzles of the nozzle row, wherein
• 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,
• 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,
• the second case has a side wall defining the second common liquid chamber portion and disposed in the second direction of the second case and a coupling port disposed in the direction opposite to the first direction from a second surface of the second case joined to the first case so that the liquid flows in from an outside or the liquid flows to the outside, and
• the side wall defines the second common liquid chamber portion and has a tapered surface separating from the coupling port in the second direction from the coupling port in the first direction.

• the second case has a second opening formed in a second surface of the second case directly joined to the first case in order to define the second common liquid chamber portion, and
• the first opening is directly connected with the second opening so that the first common liquid chamber portion is in communication with the second common liquid chamber portion.
