Abstract
A liquid ejecting head and a recording device are disclosed. The liquid ejecting head includes a fluid channel member and compressing members. The fluid channel member is elongated in a first direction. The fluid channel member includes ejection holes, compression chambers and a manifold. The compressing members is bonded to the fluid channel member. The manifold includes: a length extending in the first direction; openings at the first and second end portions of the fluid channel member; and secondary manifolds divided by one or more partitions that are elongated in the first direction. The compression chambers connected to one of the secondary manifolds configure two compression chamber rows disposed along the secondary manifolds, and the compression chambers belonging to the two compression chamber rows do not overlap in the first direction with compression chambers belonging to compression chamber rows adjacent to the two compression chamber rows.
