A jig (1) is inserted into a hollow part that is surrounded by an inner peripheral surface of a cylindrical part of a material to be molded and formed in one direction. The jig (1) is provided with: a plurality of mold parts (2) that have a contact surface having a shape complying with the inner peripheral surface and are arranged in a line in a direction crossing the one direction; a bladder (3) that is provided on a side opposite to the contact surfaces of plurality of mold parts (2) with respect to the mold parts (2), capable of accommodating a fluid (10) therein, and expandable/retractable in accordance with a pressure of the accommodated fluid; a joining part that joins the plurality of mold parts (2) and the bladder (3) together; and a connection part (5) that connects a one-side mold part (2) and an another side mold part (2) adjacent to the one-side mold part (2) among a plurality of mold parts (2) to each other and restricts an interval between the one-side mold part (2) and the other-side mold part (2) in a direction crossing the one direction with a prescribed range.
