An article supply device includes a storage unit in which a plurality of articles are stored, a supply path, a partition/passing-through member that forms a predetermined gap between a surface of the supply path and the partition/passing-through member, a driving unit that allows the supply path and the partition/passing-through member to relatively move each other, and a gas injection unit that injects gas to the articles on the supply path in at least one of the upstream and the downstream of the partition/passing-through member.
