Abstract

A device for manufacturing a fiber-reinforced resin having an array of reinforcing fibers oriented in one direction, the device making it possible, with a comparatively simple configuration, to connect earlier and later reinforcing fibers to each other when switching the reinforcing fibers, is provided. The device having an array of reinforcing fibers oriented in one direction according to the present invention comprises: an impregnation unit that impregnates reinforcing fibers with a resin; and a switching device that, when the reinforcing fibers to be impregnated are changed to new fibers, connects the newly fed reinforcing fibers to the previously fed reinforcing fibers. When switching the reinforcing fibers, the device connects the new reinforcing fiber to the preceding reinforcing fiber by forming a bonded body in which the preceding reinforcing fibers and the new reinforcing fibers are bonded by fusing a melted second resin in a form of a thin film.
