PROBLEM TO BE SOLVED: To safely and efficiently fill a container with a granule by filling the granule while making nitrogen gas flow in the container in the case of filling the container with the granule. SOLUTION: As a granule of an inorganic material and an organic material to be filled, although no particular restriction is applied, the granular of 250-1000μm average particle diameter is preferred, 500-850μm is more preferable, and to be concrete, a vinyl alcohol resin, a vinyl chloride resin, an acrylic resin, a polyester resin or the like can be used. In the case of filling a container (a) with the above granule, nitrogen gas is exhausted outside the container from, an exhaust outlet, while introducing the granule and the nitrogen gas from an introduction inlet. Namely the granule is mixed into the nitrogen gas just before the introduction inlet and the granule is introduced into the container (a) while the nitrogen gas is exhausted from the exhaust outlet to outside the container (a), and the nitrogen gas is circulated by operating a blower (b) or the like and used.
