Abstract: A liquid ejecting head unit includes a first connector configured to be coupled to an external wiring member. The liquid ejecting head unit includes a wiring board having the first connector, a housing for the liquid ejecting head unit, the housing having an opening through which the first connector is exposed outside and having a housing space accommodating the wiring board, and a flexible member in the housing space. The flexible member separates the housing space into a first space that has at least a portion of the first connector and the opening and a second space that is larger than the first space.

Abstract: A head unit includes: heads including a first-head and a second-head including respective flow channels, and a common flow channel member being stacked on the heads and including common flow channels communicating with the heads in common; flexible members including a first-flexible-member disposed between the first-head and the common flow channel member, and a second-flexible-member disposed between the second-head and the common flow channel member; and fixation members for fixing the common flow channel member, the first and second-heads, and the first and second-flexible-members together. The first-flexible-member establishes liquid-tight communication between a first-flow-channel and a first-common-flow-channel by being compressed in a stacking direction. The second-flexible-member establishes liquid-tight communication between a second-flow-channel and the first-common-flow channel by being compressed in the stacking direction.
