A carrier reel according to the present invention is constituted by a flange portion having a first surface and a second surface which is opposed to and substantially parallel to the first surface, and a hub portion which is provided between the first surface arid the second surface and to which the flange portion is connected. A bearing portion at which a shaft used for taking out each electronic component after carriage is supported is provide to the hub portion, and spaces for accommodating therein a drying agent, i.e., drying agent accommodating portions are formed at the part of the hub portion except the bearing portion. The drying agent is accommodated in the drying agent accommodating portions. The carrier reel having the drying agent accommodated therein is put in a damp proof bag to be sealed. The sealed damp proof bag is then packaged to be carried. As a result, it is possible to provide the carrier reel by which the cubic volume of the entire package becomes constant irrespective of characteristics of electronic components to be carried and provide a carriage method using such a carrier reel.
