摘要： The present invention aims to provide a liquid discharge head that causes less deviation in a discharge direction of a liquid from a direction orthogonal to a discharge hole surface, and a recording device using the liquid discharge head. The liquid discharge head 2 of the present invention includes a discharge hole 8, a discharge hole surface 4-1 having an opening of the discharge hole 8, a pressurizing chamber 10, and a flow channel connecting the discharge hole 8 and the pressurizing chamber 10. The flow channel 13 includes a nozzle part 13a and a partial flow channel 13b. The partial flow channel 13b is formed so that a distance Dm between Cm and C1 in a planar direction is larger than 0.1 W [µm] and a distance D2 between C2 and C1 in the planar direction is 0.1 W [µm] or less, wherein W [µm] is a mean diameter, C1 is an area centroid on a side close to the nozzle part 13a, C2 is an area centroid at a position located 2W [µm] away from the side close to the nozzle part 13a, C3 is an area centroid on a side close to the pressurizing chamber 10, and Cm is an intersection of a straight line connecting C1 and C3, and a plane parallel to the discharge hole surface at a position located 2W [µm] away from the side close to the nozzle part 13a.

摘要： [Problem] The objective of the present invention is to provide: a liquid discharge head that can have a greatly reduced size in the direction of the shorter dimension while reducing crosstalk; and a recording device that uses the liquid discharge head. [Solution] The liquid discharge head (2) is provided with: a plurality of discharge holes (8); a plurality of compression chambers (10); a duct member (4) that is longer in one direction and has a manifold (5); and a plurality of compression units (30). The manifold (5) extends from one end to the other end of the duct member (4), opens to the outside at both ends of the duct member (4), and is partitioned into a plurality of sub-manifolds (5b) by a dividing wall (15) that is longer in the one direction. The compression chambers (10) connected to one sub-manifold (5b) configure two compression chamber rows (11) aligned along the sub-manifold (5b). The compression chambers (10) belonging to a compression chamber row (11) do not overlap in the one direction with the compression chambers (10) belonging to a compression chamber row (11) adjacent to the compression chamber row (11).
