A droplet producing device (1) includes an outer tube (2); and an inner tube (3) that is arranged inside the outer tube (2) and feeds a droplet raw material, in which an inner tube discharge port (3b) opens to an inner tube tip portion (3a) formed on a downstream in a fluid feed direction, an outer tube discharge port (2b) opens to an outer tube tip portion (2a) formed on the downstream in the fluid feed direction, and in which a gap (2c) is formed between the outer tube (2) and the inner tube (3). It is preferable that the inner tube discharge port (3b) be provided inside the outer tube on an upstream of the outer tube discharge port (2b) in the fluid feed direction.
