Abstract:
1. A manufacturing method of an RFID tag comprising: forming a conductive pattern and a communication antenna on a surface of a heat-softening base sheet; mounting a second semiconductor element on the conductive pattern, with a thermosetting adhesive sandwiched therebetween; heating the heat-softening base sheet mounted with the second semiconductor element, to harden the thermosetting adhesive and to form, by the heating to harden the thermosetting adhesive, a recess having a greater dimension than the second semiconductor element in a portion of the base sheet where the second semiconductor element is mounted; mounting a first semiconductor element having a greater dimension than the recess astride the recess of the base sheet; connecting the first semiconductor element to the conductive pattern; and connecting at least any of the first semiconductor element and the second semiconductor element to the communication antenna on the base sheet.
