Abstract: A liquid ejecting device is manufactured by bonding a wiring substrate to a liquid ejection head by means of an adhesive film. The liquid ejection head has a pressure chamber for ejecting liquid and an air chamber disposed adjacent to the pressure chamber with a wall of a piezoelectric body interposed therebetween. A pair of electrodes is provided, one on the wall surface of the pressure chamber and the other on the wall surface of the air chamber so as to sandwich the piezoelectric body wall. The wiring substrate has a connection terminal which is to be electrically connected at least to the electrode on the pressure chamber side at the time of bonding. The liquid ejection head has an opening for introducing liquid into the pressure chamber, while the wiring substrate has a through hole to be aligned with the opening at the time of bonding.
