Abstract: An impregnation device includes an impregnation unit, a first supply unit, a second supply unit, and a supply controller. The impregnation unit impregnates a bundle of transported continuous fibers with a resin mixture. The first supply unit supplies a resin of a first composition to the impregnation unit. The second supply unit supplies a resin of a second composition that is different from the resin of the first composition to the impregnation unit. The supply controller controls an amount of resin supplied from the first supply unit and the second supply unit to the impregnation unit.
