Patent ID: 7784908

Claim:
A liquid discharge head, comprising: a recording element substrate for discharging liquid responsive to an electrical signal from outside, the recording element substrate being disposed on a surface of the liquid discharge head; a plurality of terminals for electrically connecting with outside, and disposed on a surface of the liquid discharge head other than the surface on which the recording element substrate is disposed; and a flexible wiring board for electrically coupling the recording element substrate with the plurality of terminals, the flexible wiring board being disposed on the surface on which the recording element substrate is disposed and on the surface on which the plurality of terminals are disposed and comprising: a base film substrate; and a plurality of wires being disposed on the base film substrate and arranged along a width direction of the base film and covered with a film material bonded to the base film substrate; wherein the flexible wiring board includes a flexing part to be bent along the width direction, and each wire to be formed in the flexing part, curves toward an inside of the base film substrate, and wherein, in the flexing part, a curvature of the wire, to be formed in an end portion in the width direction, is larger than a curvature of the wire to be formed in the center in the width direction.
