Jig and method for manufacturing boxed body of polycrystalline silicon

A jig comprising:

• a side surface body that has a tubular shape and that forms an insertion space into which an accommodation bag accommodating polycrystalline silicon fracture piece is to be inserted from above;
• lift portions that are provided to the side surface body in order to lift the accommodation bag and the side surface body;
• and
• a tray that is detachably provided to a bottom portion of the side surface body and that is configured to support the accommodation bag,
• the tray being configured to, when the side surface body is lifted, be detached, so that an opening is formed at the bottom portion of the side surface body,
• the opening being configured to form, when the accommodation bag is placed from above into an accommodation space in which the accommodation bag is to be accommodated, a placement path for the accommodation bag from the insertion space to the accommodation space,
• wherein the opening fits in a cross section of the accommodation space cut along a plane substantially parallel to a horizontal plane.
