PROBLEM TO BE SOLVED: To provide a liquid discharge head hardly causing cracks because of lamination during a manufacturing process, and a recording device using the same.SOLUTION: A liquid discharge head includes a discharge hole 8, a compression chamber 10 connected to the discharge hole 8, a flow path member 4 having a compression chamber surface 4-2 in which the compression chamber 10 is opened, and a displacement element substrate 21 having a ceramic vibration plate 21a stacked on the compression chamber surface 4-2 of the flow path member 4. The ceramic vibration plate 21a and the compression chamber surface 4-2 are stacked together via a plurality of adhesive layers. The adhesive layer (second adhesive layer 39) of the compression chamber surface 4-2 side is softer than that (first adhesive layer 38) of the ceramic vibration plate 21a side. |
