Abstract
Tensile strength of a tape layer in the lengthwise direction is selected to be higher than adhesive force of the tape layer to optical fiber cores. Further, position limiting portionsby which the positions of a plurality of optical fiberscan be limited are formed in a flexible filmfor tape core assembly which film is used for integrating the plurality of optical fibersas a tape. Further, a ribbon-like optical fiber core assemblyaccording to the invention including a plurality of optical fiber coresarranged planarly at designated intervals, an adhesive layerdisposed so as to surround the optical fiber cores, and filmsandintegrated with the optical fiber coresby the adhesive layer
