Abstract:
An electronic device includes a sealing plate including a first surface connected to a pressure chamber formation substrate, and a second surface having a drive IC provided thereon. The sealing plate includes a first region in which a plurality of individual connection terminals are arranged, and a second region in a position different from the first region. A plurality of bump electrodes are arranged at a pitch different from a pitch of an individual connection terminals, in a region overlapping a second region, and a wiring group connecting the individual connection terminal and a bump electrode includes a first wiring of which a position of a pass-through wiring relaying the first surface and the second surface is within the first region. A second wiring of which a position of a pass-through wiring connecting the first surface and the second surface is within the second region.
