Patent ID: 8303090

Claim:
A liquid discharge apparatus which discharges a liquid, comprising: a liquid discharge head including: a channel unit which is formed with nozzles through which the liquid is discharged and channels for the liquid; and driving sections which have electrodes corresponding to the nozzles and which are driven so that a driving signal is applied to the electrodes to apply a discharge pressure to the liquid in the channel; bump-shaped terminals which are formed of a conductive material having conductivity and which are arranged on the electrodes; and a wiring board including: a base board which is arranged to face a surface of the liquid discharge head formed with the electrodes, and in which hollow portions are formed at portions, of the base board, facing the terminals; thermally expandable members provided in the hollow portions of the base board; and lands which are formed, on a first surface of the base board facing the liquid discharge head, to face the terminals and which cover at least a part of the thermally expandable members, such that the lands are arranged between the thermally expandable members and the terminals; wherein the terminals are provided at positions shifted from positions overlapped with the driving sections, as viewed in a direction perpendicular to a surface of the liquid discharge head on which the electrodes are formed; and wherein the lands are extruded toward the liquid discharge head, as compared with surroundings of the lands, so that the lands abut against the terminals.
