A method of manufacturing a prepreg. The method includes step (I) of dispersing a reinforcing fiber bundle to obtain a reinforcing fiber base material, step (II) of providing a binder to the reinforcing fiber base material produced in the step (I), and step (III) of hybridizing a matrix resin composed of a thermoplastic resin with the reinforcing fiber base material provided with the binder produced in the step (II), wherein the steps (I) to (II) are carried out online and the prepreg is one such that the content of the reinforcing fiber bundle relative to the whole portion of the prepreg is from 10 to 80% by mass, the content of the binder relative to the whole portion of the prepreg is from 0.1 to 10% by mass, and the content of the matrix resin relative to the whole portion of the prepreg is from 10 to 80% by mass. |
