The elastic yarn wound body package comprises a paper tube and an elastic yarn wound body, wherein: the paper tube has a groove in the circumferential direction, perpendicular to the paper tube axis, between an end portion of the elastic yarn wound body and an end portion of the paper tube; a tail yarn of the elastic yarn wound body is wound into the groove; and a wire-shaped object or tape-shaped object that crosses at least a portion of the yarn bundle of the tail yarn is held thereby. Also provided are paper tubes comprising, in the vicinity of at least one end, a tail thread wrapping groove having parallel edges along a circumferential direction perpendicular to the axis of the paper tube, the paper tube comprising a recession, the maximum width of which is greater than the width of the tail thread wrapping groove and the deepest part of which is deeper than the tail thread wrapping groove, over the tail thread wrapping groove or an extension of the tail thread wrapping groove and elastic thread reel packages comprising these paper tubes.
