1. 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.

5. A shaping method for shaping the laminate using the molding die described in claim 1, the shaping method comprising:
laying the laminate on the kink surface; and
bending, toward the placement surface along the bending line, the laminate laid on the kink surface.
