ABSTRACT:
An inkjet print head for which an ink flow path formation member, arranged on a printing element board, is prevented from being peeled off or being damaged, and the printing element board in an appropriate state can be mounted on a support member. According to the present invention, an ink flow path formation member is arranged on one face of a printing element board, and a peripheral area extending outward from the ink flow path formation member is prepared. Since pressure is applied to the peripheral area using a mounting tool, to bond the first terminals of the printing element board to the electrode terminals of the support member, damage to the ink flow path formation member, caused by the mounting tool, can be prevented.
