Claim 4:
5. The composite material structure manufacturing jig according to claim 4, wherein
the reinforcement structure includes a lower-base-side outer surface and an upper-base-side outer surface,
the upper-base-side outer surface is positioned on an opposite side of the reinforcement structure from the lower-base-side outer surface,
the reinforcement structure is disposed inside the tubular body so that the lower-base-side outer surface has a width corresponding to an inner surface of the lower base, and the upper-base-side outer surface has a width corresponding to an inner surface of the upper base,
an outer surface height of the reinforcement structure is less than an internal height of the tubular body,
the internal height of the tubular body is a distance between the inner surface of the lower base and the inner surface of the upper base,
the outer surface height of the reinforcement structure is a distance between the lower-base-side outer surface and the upper-base-side outer surface of the reinforcement structure, and
in a state where the upper-base-side outer surface is in contact with the inner surface of the upper base, the lower-base-side outer surface is not in contact with the inner surface of the lower base, with a gap formed between the lower-base-side outer surface and the inner surface of the lower base.
