PROBLEM TO BE SOLVED: To provide a liquid discharge head with less variation of discharge characteristics due to resonance of the liquid discharge head, and a recording device using the same.SOLUTION: A liquid discharge head includes a flow channel member 4 having a plurality of discharge holes and a plurality of compression chambers 10, and a piezoelectric actuator substrate 21 having a plurality of displacement elements respectively pressurizing liquid in the plurality of compression chambers 10. The plurality of compression chambers 10 are arranged in such a manner that they are divided into a plurality of compression chamber groups apart from each other. The plurality of displacement elements are arranged in such a manner that they are divided into a plurality of displacement element groups apart from each other. One or more grooves 32 are arranged along a boundary of the plurality of displacement element groups on a surface to which the piezoelectric actuator substrate 21 is joined in the flow channel member 4. |
