Abstract:
A liquid droplet discharging head includes: a substrate; a pressure chamber connected to the substrate; a penetrating portion formed in the substrate to discharge a liquid droplet; and a plurality of liquid droplet guiding portions formed at the penetrating portion of the substrate to guide the liquid droplet, in which each of the liquid droplet guiding portions extends with a curvature in an discharging direction of the liquid droplet.
