摘要:
A liquid ejection head includes an ejection element substrate having an energy generating element, an ejection orifice for ejecting a liquid, and a liquid supply port communicatively connected to the ejection orifice; and a support member supporting the ejection element substrate and having a liquid guide path for supplying the liquid to the liquid supply port. The support member is formed by baking a laminate including at least one guide path plate having a through-hole for constituting a part of the liquid guide path, a filter plate having an opening for disposing a filter member for filtering the liquid, and a filter member disposed in the opening.
