1. A liquid ejecting apparatus comprising:
a first liquid ejecting head configured to discharge a liquid in a first direction, the first liquid ejecting head having a first wiping surface oriented in the first direction;
a second liquid ejecting head disposed in a second direction with respect to the first liquid ejecting head, the second liquid ejecting head having a second wiping surface oriented in the first direction, the second direction being orthogonal to the first direction; and
a wiping member wiping the first wiping surface and the second wiping surface,
a third direction being orthogonal to both the first direction and the second direction,
a fourth direction being vertical to the first direction and intersecting both the second direction and the third direction,
the first liquid ejecting head and the second liquid ejecting head being arranged with a gap between the first wiping surface and the second wiping surface as viewed in a direction opposite to the first direction,
the gap including a first gap extending in the fourth direction,
the first wiping surface having a first region, the first region protruding toward the second liquid ejecting head beyond an imaginary line, the imaginary line extending in the fourth direction so as to overlap the first gap as viewed in the direction opposite to the first direction, wherein
the first liquid ejecting head includes:
first head chips arranged side by side in the second direction;
a holder having a main body to which the first head chips are fixed, and a wall erected from the main body in the first direction; and
a first fixed plate having a first surface that forms a portion of the first wiping surface, and a second surface that is opposite from the first surface and to which the first head chips are fixed,
the wall of the holder includes a third surface fixed to the second surface of the first fixed plate,
each of the first head chips includes:
a nozzle plate that forms a portion of the first wiping surface and that has nozzles through which the liquid is to be discharged; and
a case that contains a passage lading to the nozzles,
the holder has a first projection that protrudes toward the second liquid ejecting head beyond the imaginary line as viewed in the direction opposite to the first direction,
the first projection includes a fourth surface continuing to the third surface of the wall, and
the fourth surface forms the first region in the first wiping surface.
