Molding die and shaping method

A molding die for bending a laminate formed by stacking a plurality of fiber sheets, the molding die comprising:

• a kink surface on which the laminate is laid;
• and
• a placement surface intersecting the kink surface and on which the laminate is placed by bending the laminate laid on the kink surface, wherein
• the kink surface is bent so as to protrude in a second direction orthogonal to a first direction, with a kink line extending along the first direction connecting a first kink point and a second kink point as a boundary,
• the placement surface has a normal direction substantially coinciding with the first direction and has a bending line extending in a third direction orthogonal to the first direction and the second direction,
• the kink surface has a first boundary line connecting a first intersection on the bending line and the first kink point, and a second boundary line connecting a second intersection on the bending line and the first kink point,
• the first intersection is positioned closer to one end of the bending line relative to the first kink point in the third direction,
• the second intersection is positioned closer to an other end of the bending line relative to the first kink point in the third direction,
• the first kink point is positioned between the first intersection and the second intersection and the second kink point in the first direction, and
• the bending line between the first intersection and the second intersection convexly protrudes toward the kink line in the second direction.
