Abstract
It is an object of the present invention to provide a droplet discharging head suited to the discharge of a sample solution, and particularly one that contains a bio-related substance. This object is achieved by a droplet discharging head 1 for discharging a sample solution, wherein the portion of the inner walls of the droplet discharging head 1 that comes into contact with the sample solution is covered with a polymer composed of phosphorylcholine group-containing unsaturated compound units, or a copolymer including same. The droplet discharging head is preferably an electrostatic drive or piezoelectric drive type.
