Abstract: A liquid ejecting head is mounted on a carriage in which a first positioning hole defined by a first inner surface is provided. The liquid ejecting head includes a first positioning member and a first intermediate member. The first intermediate member includes a first expansion portion being capable of being inserted into a first positioning hole and abutting on the first inner surface by expanding in a radial direction intersecting with an insertion direction of the first expansion portion. The first expansion portion includes a first insertion hole into which the first positioning member is inserted and expands in the radial direction by the first positioning member being inserted into the first insertion hole.
