PROBLEM TO BE SOLVED: To achieve the simplification of manufacture while enhancing the density of discharge ports by preventing warping. SOLUTION: The liquid discharge head comprises a core substrate 70 composed essentially of fabric in which a plurality of pressure chambers 52 each communicating with a plurality of discharge ports 51, a vibration plate 56 which is added to the upper surface of the core substrate 70 and is arranged with a piezoelectric element 58, a first resin laminated part 110 which is formed on the upper side of the core substrate 70 by laminating thin resin plates 111 to 117 and is provided with a common liquid chamber 55 supplying liquid to each pressure chamber 52, a second resin laminated part 120 which is formed on the lower side of the core substrate 70 by laminating thin resin plates 121 to 127 and is provided with a plurality of discharge passages 73 for communicating the plurality of pressure chambers 52 with the plurality of discharge ports 51 respectively, and a plurality of drive wiring lines 90 for supplying a drive signal, which are formed in the first resin laminating part 110, in the direction substantially vertical to the surface where the piezoelectric element 58 is arranged so that at least a part of the drive wiring lines rises in the common liquid chamber 55.
