Abstract:
A recording head includes a substrate whose first surface has an element that generates energy used for ejecting liquid; a first portion that supports a second surface of the substrate; a wiring member having multiple electrode leads connected to multiple electrode pads provided in the substrate; a second portion that supports the wiring member; and a sealant that seals a section including a connection section between the electrode pads and the electrode leads. A region surrounded by the substrate, the second portion, and the electrode leads is provided with an ascending portion that increases in height in a direction extending from the second surface toward the first surface, the ascending portion increasing in height from a first end to a second end of the region in an arrayed direction of the electrode leads.
