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. |
