Recording head

摘要

A recording head having a substrate and a channel forming member configured to form a flow channel, a supply port formed at the substrate so as to penetrate through the substrate, the flow channel communicates with the supply port, and a member formed of an organic material and configured to connect two surfaces forming the supply port and opposing each other with the supply port interposed therebetween.

主权项

1. A recording head comprising:
a substrate and a channel forming member configured to form a flow channel; a supply port formed at the substrate so as to penetrate through the substrate and the flow channel communicates with the supply port; an interconnecting member formed of an organic material and configured to connect two surfaces forming the supply port and opposing each other with the supply port interposed therebetween, wherein the two surfaces oppose each other in a transverse direction of the supply port when viewed from above in a direction in which the supply port penetrates through the substrate; and a rigid bridge structure configured to also interconnect the two surfaces forming the supply port, while also providing an upper support surface to provide structural support for a bottom surface of the interconnecting member, so that the upper support surface of the bridge structure is in direct contact with the bottom surface of the interconnecting member, wherein the interconnecting member formed of the organic material does not connect the two surfaces opposing each other in a longitudinal direction of the supply port when viewed from above in a direction in which the supply port penetrates through the substrate, wherein the substrate is arranged in a depressed portion of a supporting member.
