A fluid material ejecting apparatus includes a material chamber to which a fluid material containing at least one of metal particles and ceramic particles is supplied, a valve seat constituting a part of the material chamber and including an ejection port, a piston movable in the material chamber in directions toward and away from the ejection port, and a driver of the piston. The driver is configured to cause the piston to contact the valve seat from a position away from the valve seat and move in the direction toward the ejection port so as to slide along the valve seat, to thereby eject the fluid material through the ejection port. Sliding surfaces of the piston and the valve seat via which the piston and the valve seat contact each other have a higher Vickers hardness than the particles contained in the fluid material.
