An ink jet recording head has a plurality of discharge energy generating devices for discharging recording liquid; a recording element base plate arranged on the face opposite the surface where the devices are arranged, having a plurality of recording liquid supply ports for supplying recording liquid to the devices; and a supporting member that holds and fixes the recording element base plate. For the supporting member, a plurality of recording liquid supply paths are arranged to supply recording liquid to the supply ports of the recording element base plate, respectively, and the width of the supply paths is formed to be smaller than the opening width of the inlet portions of the supply ports. Further, stepped portions created between the respective supply paths and supply ports are buried by a bonding agent forced out from the bonding face of the recording element base plate and the supporting member.

A liquid discharge apparatus for producing a probe carrier, having a configuration capable of supplying a discharge unit with plural probe solutions without increasing the dimensions of the apparatus, as well as a method and apparatus for producing the probe carrier utilizing such liquid discharge apparatus. The arrangement pitch of the supply openings to liquid holding portions from plural liquid discharging portions (which are provided in the liquid discharge apparatus and respectively correspond to the plural probes) is set to be larger than the arrangement pitch of nozzle openings, thereby increasing the freedom in designing the position and capacity of the liquid holding portions for holding the probe solutions.
摘要:
A method for manufacturing an ink jet recording head, which is provided with a recording elemental substrate having discharge port group for discharging ink, an electric wiring substrate electrically connected with the recording elemental substrate, and a supporting member for holding and fixing the recording elemental substrate and the electrical wiring substrate, comprises the steps of injecting thermohardening filler into a filler retaining portion communicated with the sealing area requiring sealing; filling the area with the thermohardening filler injected into the filler retaining portion by heating the filler to flow; and hardening the filled thermohardening filler. With the structure thus arranged, it is possible to eliminate any electrical and structural defects in order to materialize a highly reliable and compact ink jet recording head.
