<P>PROBLEM TO BE SOLVED: To provide a powder and granular material supply device for reducing cost required for manufacture and use, and superior in disassembling-cleaning performance, by reducing scattering and pollution of a powder and granular material with a simple structure. Ž<P>SOLUTION: This device is used when supplying the powder and granular material to a manufacturing device from a sealed container, and has a first connecting pipe 12 arranged on the sealed container side and a second connecting pipe 24 arranged on the manufacturing device side. The first connecting pipe 12 is provided with a first butterfly valve 14, and the second connecting pipe 24 is provided with a second butterfly valve 34, respectively. The two connecting pipes 12 and 24 have a cleaning nozzle 26 for cleaning a space partitioned by the two butterfly valves 14 and 34 constituted when connecting the two connecting pipe 12 and 24, to a place positioned between the two butterfly valves 14 and 34.
