To provide a storage method and a winding liner of an unvulcanized rubber member of which an occupancy space for storage can be made smaller by making the reel's length shorter in the axial direction especially when a used winding liner is reeled in.

Spacers 3, of which the height is higher than the thickness of the unvulcanized rubber member and which are laid on both sides of a non-elastic fixed-width beltlike base plate 2, is detachably laid successively along the beltlike base plate 2, to form the winding liner 1 of the unvulcanized rubber member.
