A nail print apparatus which prints on a nail. The nail print apparatus includes a partition wall and a printing section. A first surface of the partition wall is in contact with at least one first finger inserted on the first surface. A second surface of the partition wall is in contact with at least one second finger, which is different from the first finger, inserted on the second surface. The first surface and the second surface are held between the first finger and the second finger from a first end of the partition wall. A thickness of the partition wall between the first surface and the second surface increases from the first end toward a second end opposite to the first end.
