摘要：
A liquid ejection head includes channel forming members and a surface treatment film. The channel forming members are joined to each other via an adhesive agent to form a channel for liquid. The surface treatment film is formed on a surface of at least one of the channel forming members. The surface treatment film is an oxidized film including Si. The oxidized film further includes a transition metal forming a passive film.
