Configuration of ink jet print head capable of reliably maintaining its continuity

摘要

An ink jet print head 1 includes a laminated piezoelectric element 31. The piezoelectric element 31 is fixedly attached to electrodes 33 by electrically conductive adhesive 32. A flexible printed cable 16 is electrically connected to electrodes 35 by soldering. The stationary plate 15 is formed with through holes 36, which are filled with an electrically conductive filler 34. The filler 34 and the electrodes 33, 35 are formed of tungsten, and the electrodes 33, 35 are plated with gold.
