Claim Text:
1. A method for manufacturing a fiber-reinforced base material formed by stacking a base material sheet including a reinforcement fiber onto a mold having a double-curved surface shape, the method comprising steps of: supplying the base material sheet onto the mold from a base material roll wound with the base material sheet; and applying pressure to the base material sheet in contact with the mold in such a state that, before the base material sheet arrives at the mold, the base material sheet has distribution of a supplying length of the base material sheet in a width direction of the base material sheet in correspondence with the double-curved surface shape of the mold, wherein the base material roll has a circumferential length varying in the width direction so as to apply the distribution to the length of the base material sheet in the sheet-supplying direction, and wherein, while supplying the base material sheet onto the mold from the base material roll, an outer periphery of the base material roll is pressed against the mold over the base material sheet so as to apply pressure to the base material sheet in contact with the mold.
