The plurality of dicing lines include a dicing line extending in one direction and a dicing line extending in a direction crossing the one direction, and the recess is formed on each of positions overlapping the dicing lines except for an intersection part where the dicing line extending in the one direction intersects the dicing line extending in the direction crossing the one direction.

Liquid ejection head and manufacturing method thereof

A liquid ejection head includes an ejection-port formed member including liquid ejection ports, a substrate including liquid supply ports for supplying liquid to the ejection ports and a partition between the liquid supply ports, and a substrate supporting member. The liquid supply ports extend along the longitudinal direction of the substrate when viewed from a position facing the main surface of the substrate. The liquid supply ports are arrayed along the lateral direction of the substrate when viewed from the position facing the main surface. The partition includes a non-contact portion that is not in contact with the supporting member and a contact portion that is in contact with the supporting member. Of the liquid supply ports, adjacent liquid supply ports communicate with each other in the lateral direction through a gap between the non-contact portion and the supporting member, and liquid flows through the gap.

Liquid ejection head

A liquid ejection head includes a recording element substrate. The recording element substrate includes a recording element, a circuit wiring driving the recording element to eject liquid, a protective film, an electrode area, a plating bump, and a resin film having elastic properties. The electrode area electrically connects the circuit wiring to an external circuit through an opening in the protective film. The protective film covers the circuit wiring in an outer adjacent region to the opening to define a step in the protective film. The protective film protects the circuit wiring against the liquid. The plating bump is electrically connected to the electrode area. The resin film covers the step and extends from an inner peripheral region of the opening onto the protective film beyond an edge of the opening. The plating bump includes a part projecting from the electrode area onto an upper surface of the resin film.

Liquid cartridge
