A spinning die for melt-blowing employed in a device for manufacturing a nonwoven fabric using a melt-blowing method, the die comprising: a plurality of supply passages for supplying molten plastic; a hot air passage; and an opening surface in which a plurality of discharge ports and a plurality of blowing ports (15A, 15B) open, wherein each of the discharge ports discharges the molten plastic supplied through the corresponding one of the supply passages, and each of the blowing ports (15A, 15B) is arranged in correspondence with one of the discharge ports and blows hot air flow supplied through the hot air passage, wherein the die spins the molten plastic discharged from the discharge ports by blowing hot air flow blown from the blowing ports (15A, 15B) onto the molten plastic, each of the blowing ports (15A, 15B) includes a main portion (16A, 16B), adjacent and closest two of the discharge ports are first and second proximate discharge ports, one of the blowing ports (15A, 15B) that corresponds to the first proximate discharge port is a first proximate blowing port, one of the blowing ports (15A, 15B) that corresponds to the second proximate discharge port is a second proximate blowing port, characterized in that the first proximate blowing port includes a guide portion that is continuous with the main portion of the first proximate blowing port and projects away from a center of the first proximate discharge port to guide the hot air flow in a projecting direction of the guide portion, and the guide portion is formed such that, as a distance from the opening surface increases, the hot air flow guided by the guide portion flows to be separated away from the hot air flow blown onto the molten plastic, which is discharged from the second proximate discharge port, through the main portion of the second proximate blowing port. a plurality of supply passages for supplying molten plastic; a hot air passage; and an opening surface in which a plurality of discharge ports and a plurality of blowing ports (15A, 15B) open, wherein each of the discharge ports discharges the molten plastic supplied through the corresponding one of the supply passages, and each of the blowing ports (15A, 15B) is arranged in correspondence with one of the discharge ports and blows hot air flow supplied through the hot air passage, wherein the die spins the molten plastic discharged from the discharge ports by blowing hot air flow blown from the blowing ports (15A, 15B) onto the molten plastic, each of the blowing ports (15A, 15B) includes a main portion (16A, 16B), adjacent and closest two of the discharge ports are first and second proximate discharge ports, one of the blowing ports (15A, 15B) that corresponds to the first proximate discharge port is a first proximate blowing port, one of the blowing ports (15A, 15B) that corresponds to the second proximate discharge port is a second proximate blowing port, characterized in that the first proximate blowing port includes a guide portion that is continuous with the main portion of the first proximate blowing port and projects away from a center of the first proximate discharge port to guide the hot air flow in a projecting direction of the guide portion, and the guide portion is formed such that, as a distance from the opening surface increases, the hot air flow guided by the guide portion flows to be separated away from the hot air flow blown onto the molten plastic, which is discharged from the second proximate discharge port, through the main portion of the second proximate blowing port.
