More Information
Summary:A liquid ejection head includes a first recording element substrate, a second recording element substrate, and an electric wiring substrate. The first and second recording element substrates each includes an energy generating element that generates energy for ejecting a liquid, and an electroconductive protective film that is disposed so as to cover at least the energy generating element. The electric wiring substrate includes wiring for supplying electric power to the first and second recording element substrates. The electroconductive protective film of the first recording element substrate and the electroconductive protective film of the second recording element substrate are electrically connected to each other through the electric wiring substrate.
