To provide a non-contact IC label configured to disable a communication function of a non-contact IC medium when the label is removed from an object by use of heat.

The non-contact IC medium includes at least an IC chip storing predetermined identification information and a compact antenna for allowing communication between the IC chip and an information reader.The non-contact IC medium is layered on a label base material provided with at least an adhesive layer for pasting the non-contact IC label to the object on one face of the base material, and includes a solvent-reactive electroconductive layer that exhibits electroconductivity by action of the solvent such that the solvent-reactive electroconductive layer covers at least a part of a portion where the non-contact IC medium is layered.
