CHANNEL-MEMBER STRUCTURE, LIQUID DROPLET DISCHARGE HEAD, MANUFACTURING METHOD OF LIQUID DROPLET DISCHARGE HEAD, AND IMAGE FORMATION DEVICE

PROBLEM TO BE SOLVED: To provide a channel-member structure, a liquid droplet discharge head and a manufacturing method of the liquid droplet discharge head which enable it to obtain a highly-precise joining between channel members and a stable discharge characteristic in the liquid droplet discharge head for which the channel member of at least two-layers structure consisting of a resin layer and a metal layer as the channel member composing a channel unit, and an image formation device. SOLUTION: In the liquid droplet discharge head A equipped with the channel unit B wherein two or more channel members were laminated, at least one channel member is composed of at least two layers of the resin layer and metal layer and provided with holes penetrating the channel member. The diameter of the hole formed in the resin layer is bigger than the diameter of the hole formed in the metal layer by stamping. COPYRIGHT: (C)2009,JPO&INPIT
