Liquid ejection apparatus and connection method for flexible wiring board

摘要

A liquid ejection apparatus includes a channel unit with a plurality of nozzles and pressure chambers configured to communicate with respective nozzles, and a plate provided on the channel unit to cover pressure chambers in a first direction from the pressure chambers, the plate comprising a plate surface extending along a second direction perpendicular to the first direction. The liquid ejection apparatus includes a plurality of drive elements arranged over the pressure chambers. The liquid ejection apparatus includes a plurality of contact terminals electrically connected to their respective drive elements at a terminal placement surface which is non-parallel with the plate surface and includes a portion of the terminal placement surface that is offset from the plate surface. The liquid ejection apparatus includes a flexible wiring board configured to be electrically connected to the contact terminals.
