A droplet discharging head comprises: a pressure chamber; a nozzle plate including a penetration part that couples with the pressure chamber and discharges a droplet; and a droplet guidance part having a tip positioned inside the penetration part. The tip of the droplet guidance part is free from touching an inside wall of the penetration part.

Droplet discharging head and method for manufacturing the same, and droplet discharging device

A droplet discharging head includes a nozzle supplied with a liquid substance, a meniscus moving section that moves a meniscus of the liquid substance in the nozzle, and a meniscus regulating section that is provided to an inside wall of the nozzle at a predetermined depth from an opening of the nozzle and regulates movement of an edge of the meniscus in the nozzle at the depth.

Droplet discharging head and droplet discharging device, and discharging control method

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.
