Abstract:
A liquid ejection head includes a substrate, a pressure chamber, first and second common liquid chambers, a filter for inhibiting inflow of foreign matter in liquid supplied to the pressure chamber, first and second supply openings respectively communicating with the first and second common liquid chambers, and a liquid receiving portion formed on an opposite surface of the substrate. The second common liquid chamber, the pressure chamber, and the first common liquid chamber are arranged in the listed order in a direction from an end of the substrate to a center of the substrate. The first common liquid chamber communicates with the pressure chamber via the filter, and the second common liquid chamber communicates with the pressure chamber through no filter.
