Abstract
A liquid ejecting head includes a first-positioning-portion into which a first-positioning-pin of a support body is inserted. 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. The first-region contacts 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 contact with the first-positioning-portion on a second-side which is the other side in the second-direction. The second-region does not contact with the first-positioning-portion on the first-side, and contacts with the first-positioning-portion on the second-side. The third-region does not contact with the first-positioning-portion on both the first-side and the second-side.
