摘要：Provided is an electronic device in which penetrating wires can be formed easily. The electronic device includes a sealing plate 33 having a first surface 41 to which a pressure chamber-forming plate 29 is connected and a second surface 42 which is on a side opposite from the first surface 41 and on which a drive IC 34 is provided; bump electrodes 40 which are arranged in a nozzle row direction on the first surface 41 of the sealing plate 33 and which output signals to piezoelectric elements 32; individual connection terminals 54 which are arranged in the nozzle row direction on the second surface 42 of the sealing plate 33 and to which the signals are inputted, wherein wires each of which connects one of the bump electrodes 40 to one of the individual connection terminals 54 corresponding to the bump electrode 40 each include a penetrating wire 45 formed inside a through hole 45a penetrating the sealing plate 33 and made of a conductor, the penetrating wires 45 are formed at positions away from the bump electrodes 40 or the individual connection terminals 54 in a direction perpendicular to the nozzle row direction, and each two of the penetrating wires 45 adjacent in the nozzle row direction are arranged at different positions in the direction perpendicular to the nozzle row direction.
