摘要： A method for manufacturing a liquid discharge head comprises the steps of providing a head main body having liquid flow paths, and an aperture surface having flow path openings communicated with the flow paths; providing a discharge port plate having extrusions each on the circumference of an inside opening communicated with each of the discharge ports, being on the inner face on the side opposite to the discharge port surface provided with discharge ports for discharging liquid, and a base having a substantially flat surface. For this method, the discharge port plate is arranged in a state of these surfaces formed integrally to be in contact; bonding the aperture surface and the inner face to fit the extrusions into the flow path openings by pressing the head main body and the base in the direction of the head main body and the base approaching each other with the discharge port plate between them; and separating the base from other members. With the method of manufacture thus structure, the liquid discharge head presents an excellent discharge efficiency by the provision of the extrusions that enter the flow paths from the orifice plate. It also becomes possible to manufacture a highly reliable liquid discharge head by a simpler manufacturing apparatus in a shorter period of time at lower costs.

摘要： It is an object of the present invention to ensure a desired precision in positioning an orifice plate with respect to liquid flow paths of a head main body, so as to prevent a failure liquid discharge which will possibly be caused due to a problem involved in a process of forming the orifice holes. In detail, a head main body is formed on the lower wall thereof a plurality of heating elements, has a plurality of liquid flow paths formed by dividing an internal space with a plurality of liquid flow path walls and arranged in parallel relationship with one another. On either side of the plurality of the liquid flow paths there are formed two dummy liquid flow paths. An orifice plate is formed with a plurality of orifice holes arranged in parallel with one another for discharging ink. Further, on either side of the plurality of the orifice holes there are formed two projected portions so shaped that they are capable of engaging with the opening ends of the dummy liquid flow paths. Each of the projected portions is formed with a dummy orifice hole which is not used for discharging ink during recording operation. A desired positioning can be effected by engaging the projected portions of the orifice plate with the dummy liquid flow paths.

摘要： An inkjet recording head includes a recording-element substrate having arranged therein multiple sets of nozzles that discharge ink, energy-generating elements that generate energy used for discharging the ink, and supply ports that supply the ink to the nozzles; and a sealant disposed around the recording-element substrate. The supply ports include a first supply port disposed near a first edge of the recording-element substrate and a second supply port disposed near a second edge of the recording-element substrate, the second edge being opposite to the first edge as viewed in the arrangement direction of the multiple sets. As viewed in the arrangement direction, a distance between the second edge and the second supply port is shorter than a distance between the first edge and the first supply port, and a volume of the sealant near the second edge is smaller than a volume of the sealant near the first edge.
