    摘要： A liquid ejection head body includes a substrate and a channel forming member arranged on the substrate. The channel forming member has a liquid ejection port for ejecting liquid and a liquid channel communicating with the liquid ejection port, while the substrate has an ejection energy generating element for generating energy for ejecting liquid at a first surface side and a liquid supply port for supplying liquid to the liquid channel in the inside. A conductive layer for electrically connecting the first surface side and a second surface side disposed opposite to the first surface side is arranged along the lateral surface of the liquid supply port.
