The present invention provides an electrode material package, by which the electrode materials are protected from damages due to external impacts, etc. during the transportation or storage. Further, with the electrode material package of the present invention, the electrode material can be kept under a low humidity atmosphere, and the term over which the quality of the electrode material is guaranteed can be prolonged. The electrode material package 20 has a roll of the electrode material 1 wound onto a winding core 2; a pair of flanges 21, of which the side faces 21 a have larger dimensions than the roll of the electrode material 1, holding both sides of the roll of the electrode material 1 through a pair of cushion materials 22; and a bag 19 made of a package film 10. The package film 10 of the bag 19 includes a moisture proof layer 12 of an aluminum foil and an intermediate layer 13 of an oriented nylon, which is located inside of the moisture proof layer 12 and faces the electrode material 1. |
