1. A liquid ejecting head configured to be supported by a support body having a first positioning pin and configured to eject a liquid, comprising:
a first positioning portion that positions the liquid ejecting head with respect to the support body by inserting the first positioning pin,
wherein when a virtual cylinder inserted to a deepest position of the first positioning portion and having a maximum cross-sectional area when viewed in a first direction which is a depth direction of the first positioning portion is defined as a first virtual cylinder, a side surface of the first virtual cylinder includes a first region, a second region, and a third region disposed between the first region and the second region, as three regions divided in the first direction,
the first region comes into contact with the first positioning portion on a first side which is one side in a second direction orthogonal to the first direction, and does not come into contact with the first positioning portion on a second side which is the other side in the second direction, with respect to a first center line which is a center line of the first virtual cylinder,
the second region does not come into contact with the first positioning portion on the first side, and comes into contact with the first positioning portion on the second side, with respect to the first center line, and
the third region does not come into contact with the first positioning portion on both the first side and the second side, with respect to the first center line.
