PROBLEM TO BE SOLVED: To facilitate optical axis adjustment of an ink droplet sensing device in which the optical axis of the ink droplet sensing device is brought into parallelism with a nozzle hole row arranged in an ink droplet discharge head on the body side of an inkjet recorder. SOLUTION: A light emitting element holder 40 is attached to a base member 28 rotatably about a light emitting side positioning hole 34 formed in a light emitting side positioning place on the base member. Meanwhile, a light receiving element holder 45 is attached to the base member slidably in a direction perpendicular to the direction of adjusting the rotation of the light emitting element holder in a position of a light receiving side positioning hole 35 formed in a light receiving side positioning place on the base member. As a result, the ink droplet sensing device 20 is attached to a housing 10 of the body of the inkjet recorder in the state of being positioned both at the light emitting side positioning place and the light receiving side positioning place.
