  • Publication number: 20200139703
    Abstract: A liquid ejection head includes a pair of electrodes disposed on a first surface of a substrate forming part of a flow path for a liquid. The pair of electrodes are adjacent to each other in a transverse direction of the electrodes, and the liquid moves in the transverse direction upon application of a voltage across the electrodes. The electrodes each include a ridge portion disposed on the first surface and an electrode wiring line connected to a power source for applying the voltage. The electrode wiring line covers an upper surface of the ridge portion and side surfaces of the ridge portion and extends from parts covering the side surfaces of the ridge portion to a downstream side and an upstream side in a direction in which the liquid moves, so as to cover the first surface.
