PROBLEM TO BE SOLVED: To provide a liquid discharge head which is hardly affected by a standing wave generated in a common flow path, a liquid discharge device using the liquid discharge head, and a recording device. SOLUTION: The liquid discharge head includes: a plurality of liquid discharge holes; a plurality of liquid pressure chambers connected to the plurality of liquid discharge holes respectively; a tubular common flow path long in one direction, connected to the plurality of liquid pressure chambers; a liquid supply path which is connected to both ends of the common flow path and whose cross-section is larger than that of the common flow path; and a plurality of pressure parts pressurizing liquids in the plurality of liquid pressure chambers respectively. The liquid discharge head in which the cross-section of the central part of the common flow path is smaller than that of the both ends of the common flow path is used. COPYRIGHT: (C)2011,JPO&INPIT
