PROBLEM TO BE SOLVED: To produce a plurality of conductive portions on a basis substrate in a simple method, in an RFID medium in which identification information is added to each conductive portion.SOLUTION: In manufacturing an ID card including a plurality of figure antennas having digits constituting a user ID on a card substrate 2, a plurality of planar conductive layers 20a-20h corresponding to the figure antennas are stacked on the card substrate 2 having a peeling layer 9, a pressure sensitive adhesive layer 6 stacked on a sheet 3 for peeling is opposed to the conductive layers 20a-20h, and the digits constituting the user ID are impressed on the conductive layers 20a-20h via the sheet 3 for peeling and the adhesive layer 6.SELECTED DRAWING: Figure 2 |
