A liquid ejection head includes an element substrate for ejecting liquid, a support member to which the element substrate is fixed, an electric wiring board arranged onto the support member and electrically connected to the element substrate by an electric connection portion, a sealant sealing the electric connection portion, and a cover member. The cover member is fixed onto the support member, and disposed to avoid the electric connection portion and the element substrate. In a direction parallel with a surface of the element substrate, the cover member includes a part facing an outer periphery of the element substrate, and, of the part, a distance to the outer periphery of the element substrate at a first surface of the cover member bonded with the support member is greater than a distance to the outer periphery of the element substrate at a second surface that is opposite to the first surface.
