Abstract:
1. A connection structure of a flexible wiring substrate for electrically connecting an inkjet head to a circuit board that supplies a drive signal that is applied to the inkjet head; wherein the inkjet head comprises a plurality of channels that eject ink onto a recording medium and a plurality of head terminals to which the drive signal is applied for ejecting ink from the plurality of channels; wherein the flexible wiring substrate has a plurality of terminal lands arranged respectively corresponding to the plurality of head terminals on one face of a strip-shaped insulator having flexibility, a plurality of leads being independently connected with the respective plurality of terminal lands; wherein the one face of the insulator is covered with an insulating film and a plurality of exposure holes are provided in the insulating film that respectively expose the plurality of terminal lands; wherein the terminal lands and the head terminals are directly electrically connected by conductive adhesive getting into the plurality of exposure holes; and wherein the insulator film of the flexible wiring substrate facing the peripheral region of the inkjet head is directly connected with the peripheral region through conductive adhesive.
