A manufacturing method for an ink jet recording head. The method includes the steps of preparing a recording element substrate, preparing an electric wiring member, preparing a sealing material discharging member, and applying a sealing material. The ink jet recording head is constructed to provide a first gap between a recording element substrate and an inner edge of a hole. The first gap is larger than a second gap between the recording element substrate and an opposite inner edge of the hole measured along the same line. The sealing material is applied while moving the sealing material discharging member, along the line, from a portion of an electric wiring member adjacent to the first gap, across the first gap, across the electrical connection portions, across the second gap, to a portion of the electric wiring member adjacent to the second gap.

The ink jet cartridge includes a tank case that has a space having a opening, a lid that closes the opening, an ink accommodating section that is formed with the space of the tank case and the lid, and an ink absorber that is accommodated in the ink accommodating section. Also, an atmosphere communication port that passes through the lid and a projection section that projects to the space of the tank case are provided in the lid. The ink absorber consists of a fiber aggregate, and a welding section in which the fibers are combined to each other and an unwelded section in which the fibers are not combined to each other are provided on a surface that faces the lid.

A predetermined amount of an ink absorber, which is a fiber assembly in which intersections between fibers are not fused together, is charged into a compression and insertion apparatus. A rectangular parallelepiped-shaped insertion block is moved to an upper surface portion of the absorber, and one face of the ink absorber is pushed by a side plate. As such, a part excluding the part of the ink absorber which faces the side plate is compressed and surrounded. In this state, the ink absorber is compressed by the side plate. The ink absorber is inserted into a tank case by making a bottom plate slide, thereby opening the bottom face of the ink absorber and by moving down the insertion block.

The liquid jet recording head includes a recording element substrate provided with a discharge port, and an electrode portion receiving a signal for controlling the discharge of the liquid droplet from the discharge port; a flexible wiring member provided with an opening, a flying lead protruding from the peripheral edge of the opening, and a film covering a portion of the flying lead; a sealant covering an electrical connection between the electrode portion and the flying lead; and a supporting member to which the recording element substrate and the flexible wiring member are attached. The film overhangs along the extension direction of the flying lead to the recording element substrate from the peripheral edge of the opening to form a void between the side surface of the recording element substrate and the supporting member, thereby partitioning the void from the electrical connection.

An inkjet cartridge includes an ink absorber capable of being impregnated with ink and an ink-absorber container. The ink-absorber container includes a first housing containing a portion of the ink absorber and a second housing containing a remaining portion of the ink absorber which is not contained in the first housing. The first housing and the second housing are bonded together at bonding portions thereof. The ink absorber has a melted section at least in an area corresponding to the bonding portions, the processed section being formed by melting a surface of the ink absorber.
