The present invention provides a manufacturing device of metal powder capable of manufacturing high-quality metal powder and a method of manufacturing metal powder using the same. The metal powder manufacturing device (10) includes: a molten metal supply portion (20) that ejects molten metal, a cylinder body (32) that is disposed below the molten metal supply portion (20), and a coolant layer forming portion (38) for forming a coolant flow along the inner circumferential surface of the cylinder body. The coolant cools the molten metal ejected from the molten metal supply portion (20). The coolant layer forming portion (38) has a front end bent portion (38a) for stabilizing the coolant flowing toward the inner side of the radial direction from the inner circumferential surface (33) and ejecting the coolant toward the flowing direction along the inner circumferential surface (33) of the cylinder body (32).
