To provide a carrier tape which hardly causes such problems as levitation and vibration during running.

This method is to manufacture a small component packaging band material 10 which stores a small component in each of many storing recesses 14 disposed along the longitudinal direction of the band material 10 and which packages it by covering the surface of the storing recess 14 with a covering tape. With respect to the band material 10 made of a flexible material, which has compression formability, the storing recess 14 is formed by pressing a forming projected form 34 having a shape corresponding to the storing recess 14 against one face of the band material 10. Simultaneously, by pressing a correcting projected form 44 having an outer shape larger than that of the storing recess 14 against the opposite face of the band material 10, the rear face of the small component packaging band material 10 is prevented from bulging out.
