A liquid ejection head includes ejection orifices for ejecting liquid, common liquid chambers connected to the ejection orifices, common flow passages, and pitch conversion flow passages that connects the common flow passages and liquid chambers to each other. The pitch conversion flow passages includes a periphery formed with resin. In a case where a number of pitch conversion flow passages in a group is minimum on a condition that one or more of the pitch conversion flow passages are respectively included in the group, the pitch conversion flow passages have a repeating pattern in which the group is repeatedly arranged. At least one of two pitch conversion flow passages adjoining an m-th pitch conversion flow passage (m is all integers from 1 to n−2, where n is an integer of 3 or more) is one of first to (m+1)-th pitch conversion flow passages.
