ABSTRACT:
A liquid ejecting head unit includes a chip head and a unit frame connected to the chip head. The chip head includes ejection outlets, flow paths, a first common liquid chamber for supplying liquid to the flow paths, a supply member having a liquid supply path for supplying the liquid to the first common liquid chamber, and energy generating elements. The unit frame has a second common liquid chamber for accommodating the liquid to be supplied to the supply member. A porous member is provided between the liquid supply path of the chip head and the second common liquid chamber of the unit frame. A connecting portion between the chip head and the unit frame is disposed upstream of the porous member, and the porous member is inclined relative to the liquid flow direction.
