Apparatus for producing a bagworm silk thread, and method of producing long bagworm silk thread

A method of producing a long bagworm silk thread, comprising:

• a spinning process of making a bagworm or the bagworm having a nest 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 used for thread production, and is configured such that the legs of the bagworm can hold the rail;
• a contacting process of bringing a bagworm silk thread on the rail in contact with a peeling solution and/or vapor;
• and
• a collection process of peeling the bagworm silk thread from the rail after the contacting process to collect the bagworm silk thread,
• wherein 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 the 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.
