ABSTRACT:
A structure for connecting an inkjet recording head, including an actuator on which connecting terminals are disposed to apply therethrough drive voltage to respective channels formed in the head for ejecting an ink droplet onto a recording medium, to a circuit element through which control signals for controlling an operation of the head are supplied, is disclosed. The circuit element is disposed on a wiring board having bump electrodes formed thereon. The connecting terminals are superposed on and connected to the bump electrodes. Each connecting terminal comprises a surface electrode having a small thickness, and an external electrode having a large thickness and formed on the surface electrode. A part of the surface electrode has a width larger than that of the other part, and the external electrode is disposed such that a margin thereof is positioned on an inside of a periphery of the wide part.
