Abstract
A tape reel comprising a first flange having a hub formed with a plurality of coupling pawls on the top face and a second flange integrally coupled with the hub by fitting the coupling pawls respectively into a plurality of openings formed thereon. The respective pawls are so arranged on the bridge-shaped portions formed on the top of the hub that the hook portions are directed to the center of the hub in order to ensure the coupling between the hub and second flange and the edge portions of respective openings to be engaged with the hook portions are depressed to a depth so as to be able to correspond to the thickness of the second flange and the coupling pawls are so formed that the engaging faces of respective hook portions are on the same level as of the top face of the hub.
