Abstract
A liquid ejecting apparatus includes a head unit capable of ejecting a liquid from a nozzle provided in a nozzle surface of a nozzle plate, an anchoring plate in which the head unit is anchored and that is provided with an opening region that exposes the nozzle surface, and a wiper member that wipes an anchoring plate exposed-surface located on the opposite side of the head unit of the anchoring plate and the nozzle surface. When an angle of contact between the nozzle surface and the liquid is taken as θn, an angle of contact between the anchoring plate exposed-surface and the liquid is taken as θs, and an angle of contact between the wiper member and the liquid is taken as θw, the relationship θn>θs>θw>90° is fulfilled.
