The composite material structure manufacturing jig () is inserted in the channel of the frame component and used therein. The jig () includes a tubular body () formed of an elastic material containing a reinforcement fiber, the body () including a trapezoidal transverse section that is a cross section orthogonal to a longitudinal direction of the body (), the trapezoidal transverse section including an upper base and a lower base longer than the upper base. An inner surface of the body () is coated with an inner peripheral film () serving as a gas barrier layer.
