In a device to deliver a powdery medicine for a nasal cavity of the invention, positioning guides 12a, 12b for causing a capsule to slide as far as a predetermined position is placed on this side of cutters 11a, 11b for making holes on both ends of the capsule loaded between the connection port 7 on the side of a nozzle for spraying the powdery medicine into a nasal cavity and a connection port 8 on the side of a pump for supplying spray air to the nozzle in order to make the size of the holes made on both ends of the capsule 4 constant, and a distance L between the connection ports 7 and 8 is made shorter than a distance M between blade tips of the cutters 11a and 11b (length of the capsule 4 after cutting off the both ends by the cutters 11a, 11b), for preventing scattering of the powdery medicine in the capsule from both ends of the capsule 4 loaded between the connection ports 7 and 8, so that both ends of the capsule 4 loaded between the connection ports 7 and 8 are pressed by peripheral edges 14, 15 of the connection ports 7, 8.
