A liquid discharge head includes a supply connector, a signal connector, and a cover. The supply connector is connectable to a supply path to be supplied with a liquid from the supply path. The signal connector is connectable to a signal wire through which an electrical signal is transmitted. The cover is movable between an exposing position where the signal connector is exposed to be connectable with the signal wire and a covering position where the cover covers the signal connector from which the signal wire is disconnected.
