PROBLEM TO BE SOLVED: To provide a rewritable label using a reversible information display panel, capable of reducing a cost and man-hours for manufacturing, and efficiently suppressing the consumption of resources. SOLUTION: The rewritable label 1 comprises a reversible dry-type information display panel where display media are encapsulated in an enclosed space between two mutually facing substrates, at least one of which is transparent, and which displays required information on the transparent substrate, by moving the display media in an electric field generated by a charge formed on the surface of the substrate. The rewritable label is constituted, in such a manner that (1) two kinds of display media of different colors and charging characteristics are used, (2) the mean particle size of particles for the display media used for the information display panel falls in the range of 3-10μm, and (3) the total thickness of the information display panel falls in the range of 10μm or large and smaller than 1 mm, and the label can be attached to a curved part 3 of an object 2, to which the label is attached in a freely removable manner.
