PROBLEM TO BE SOLVED: To provide a liquid droplet delivering apparatus capable of sufficiently ensuring cross-talk preventing performance. SOLUTION: A common liquid room 40 has a main room 40a in which a communicating opening 41a communicating with a plurality of pressure rooms 42 is arranged and a flow path area of a cross-section intersecting orthogonally to the extending direction is substantially constant, a first narrow part 40b which is formed on one end side in the extending direction of the main room 40a and in which the flow path area of the cross-section intersecting orthogonally to the extending direction is smaller than the main room 40a, a first sub-room 40c which communicates with the main room 40a through the first narrow part 40b and in which the flow path area of the cross-section intersecting orthogonally to the extending direction is larger than the first narrow part 40b, a second narrow part 40d which is formed on the other end side in the extending direction of the main room 40a and in which the flow path area of the cross-section intersecting orthogonally to the extending direction is smaller than the main room 40a and a second sub-room 40e which communicates with the main room 40a through the second narrow room 40d and in which the flow path area of the cross-section intersecting orthogonally to the extending direction is larger than the second narrow part 40d.
