PROBLEM TO BE SOLVED: To provide a thin-plate-shaped or sheet-shaped body to be transferred with a strongly hooking part in the rotating direction of a feed roller to convey the thin-plate-shaped or sheet-shaped body with higher reliability and to make it easy to maintain the hooking effect of the hooking part even with the lapse of time. SOLUTION: In a feed roller 1 having on at least a portion of its peripheral surface a hook part 2 consisting of a plurality of projections 3, 3... having pointed top ends 3a thrust into a thin-plate-shaped or sheet-shaped body S, each of the plurality of projections 3, 3... constituting the hook part 2 is formed in the shape of a quadrangular pyramid with the top end 3a biased in the normal rotating direction Ra of the feed roller 1.
