Abstract
A liquid ejection head to be sterilized includes: an ejection element substrate with an ejection port surface in which an ejection port for ejecting a liquid is formed; and a liquid storage part that stores the liquid to be supplied to the ejection port. A method of sterilizing the liquid ejection head includes: covering at least the ejection port surface with a protection member in a non-contact manner; making a liquid ejection head assembly by housing the protection member and the liquid ejection head or covering the protection member's opening portion with a sheet member that is vapor permeable at least at one portion so as to block entry of bacteria into the liquid ejection head; and performing vapor sterilization on the assembly.
