To provide a brazing filler metal sheet production device and a method for producing a brazing filler metal sheet where the slipping off of powder in rolling rollers is suppressed, and a fixed amount of powder is fed to a space between the circumferential face of the rolling roller and the circumferential face of the rolling roller per unit time.

Regarding a brazing filler metal sheet production device where a treatment including a rolling treatment in which metal powder is rolled between the circumferential face of a rolling roller 4a and the circumferential face of a rolling roller 4B, so as to be molded is performed, thus a brazing filler metal sheet provided with a brazing layer having a brazing filler metal composition is produced, in the case the metal powder 2 comprises a ferromagnetic substance, the device is provided with magnetism generators 10a, 10B, 4A, 4B acting magnetism to the metal powder 2 composed of a ferromagnetic substance in a direction to be drawn to the circumferential faces of the rolling rollers.
