摘要

PROBLEM TO BE SOLVED: To stably discharge ink drops by sufficiently pressuring a predetermined wide area of a pressure generation chamber. ;SOLUTION: Island parts 11 of a rivet-like section are formed by electroforming to agree with an arrangement pitch of pressure generation chambers and continue with thick parts 14 via narrow parts 11a, 11b elastically deformably at both end parts in a longitudinal direction of the pressure generation chambers. The island parts are fixed to an elastically deformable polymer film 10.;COPYRIGHT: (C)2000,JPO
