Deadhesion of an IC tag inlet during vulcanization molding of tire is suppressed, while preventing adhesion of a portion other than a sticking out portion. An IC tag comprises a sheet-like IC tag inlet 2 , a protective cover 3 of an unvulcanized rubber sheet adhered to the surface Sf of the inlet 2 through a primer layer 10 and an adhesive layer 11 , and an antiadhesive layer 4 formed on the rear surface Sr of the inlet 2 , wherein a maximum value Ga′max of storage shear modulus Ga′ of a rubber of the protective cover 3 at a temperature of 150 to 200° C. and a storage shear modulus Gb′ 0 of the primer layer 10 at a temperature T 0 showing the maximum value Ga′max satisfy the following equation: Ga′max×10 −2 <Gb′ 0. |
