Provided is a fiber bundle adhesion method whereby a fiber-reinforced molded article can be obtained in a short period of time. Specifically provided is a fiber bundle adhesion method for adhering a fiber bundle A to an adhesion surface 5a using a thermosetting adhesive, wherein a thermosetting adhesive is applied to the fiber bundle A and/or the adhesion surface 5a, whereafter the fiber bundle A is pressed to the adhesion surface 5a so as to adhere the fiber bundle A to the adhesion surface 5a while simultaneously impregnating the thermosetting adhesive into at least a part of the fiber bundle A.
