Abstract: A liquid discharge apparatus includes a discharge head including a discharge surface formed with a plurality of discharge openings from which a liquid is discharged, a cap configured to be detachably attached to the discharge head and form a holding space for a cleaning liquid such that the cleaning liquid contacts the discharge surface, a supply portion configured to connect to the cap and to supply the cleaning liquid to the holding space, and an outlet portion configured to connect to the cap and to drain the cleaning liquid from the holding space. The supply portion is formed at a position facing the discharge surface. The outlet portion is formed at a position outside the supply portion in an inside-outside direction of the discharge surface.
