A signal transmittingreceiving antenna device for Radio Frequency Identification which executes contactless data communication, and a method of manufacturing the same. The present invention provides a polymeric material used in combination with a tissue adhesive, which comprises carbon or silicon as a constitutional element, and at least a portion of the surface of which is modified by ion bombardment. A ratio R1 of the diameter of the maximum dimple dmax to the diameter D of this golf ball 1 is 11. The vent crack and the modified stress zone are configured to separate the substrate along the guide path.
