1. An impregnation device comprising:
an impregnation unit that impregnates a bundle of transported continuous fibers with a resin mixture, the impregnation unit comprising a container extending in a transport direction of the continuous fibers, the container including
a pair of end walls that intersect with the transport direction,
a side wall that extends in the transport direction and between the pair of end walls,
a first supply port in the side wall permitting supply of a first composition comprised of a first resin into the container, and
a second supply port in the side wall, downstream from the first supply port in the transport direction, permitting supply of a second composition comprised of a second resin into the container, wherein the second resin is different from the first resin;
a first supply unit configured to supply the first composition to the impregnation unit via the first supply port;
a second supply unit configured to supply the second composition to the impregnation unit via the second supply port; and
a supply controller that controls an amount of the first resin supplied from the first supply unit to the impregnation unit and an amount of the second resin supplied from the second supply unit to the impregnation unit.
