1. A method of producing a bagworm silk thread from a bagworm, comprising
a spinning process of making the bagworm hold a rail with its legs and continuously spin along the rail, wherein
the rail has a width smaller than a maximum width between right and left legs of the bagworm for use, and is configured to be able to be held by the legs of the bagworm, and
in the spinning process, the bagworm separated from a nest or a nest containing the bagworm is fixed at a position such that the legs of each bagworm can hold the rail,
wherein the rail is configured to be moved in a longitudinal direction of the rail automatically and/or by a movement impelling force of the bagworm legs.
