Abstract
An ink jet cartridge has a recording head with a substrate, a head portion with a discharge port surface on the substrate, a discharge port provided on the discharge port surface, and an ink tank, the substrate having a leading end line. The ink tank has a substantially rectangular parallelopipedal shape and can contain ink. The ink tank includes a front surface, side surface, and opposing surface opposed to the side surface, the recording head is disposed on the side surface of the ink tank, and the opposing surface has a front end line. Plural positioning portions are provided on and project from the substrate of the head and part of the ink tank. The positioning portions project only within a space enclosed by a plane, the front surface of the ink tank, and the substrate. The leading end line of the substrate of the recording head and the front end line of the surface opposed to the side surface of the ink tank on which the recording head is disposed lie in the plane.
