A liquid droplet ejecting apparatus includes: a plurality of plate members which are laminated with an adhesion layer interposed therebetween; and an ink flow path for an ink, which is formed through the plurality of plate members. The plurality of plate members include: a first plate member which includes a first surface; and a second plate member which is adjacent to the first plate member and includes a second surface facing to the first surface through the adhesion layer. A work of adhesion of the ink to each of the first and second surfaces at a portion surrounding the ink flow path is 0.065 J/m2 or less.
