Abstract
A liquid discharge apparatus includes an individual flow passage member; and a common flow passage member joined to the individual flow passage member in a first direction. The individual flow passage member has nozzle groups formed on a surface on a side opposite to the common flow passage member and connecting hole groups formed on a surface on a side of the common flow passage member; and the common flow passage member has manifold flow passages corresponding to the connecting hole groups respectively. Each of the nozzle groups includes nozzles aligned in a second direction orthogonal to the first direction; and each of the connecting hole groups includes connecting holes aligned in the second direction and connected to the nozzles respectively. Each of the manifold flow passages extends in the second direction and is connected to the nozzles via the connecting holes.
