PROBLEM TO BE SOLVED: To prevent a commodity from being impaired by a corner part of a radio tag by storing a substrate where the electronic parts are packaged into a container through a top surface opening part of the container, filling the container with a resin material supplied through the top surface opening part, hardening the resin material and cutting the outer fringe part of the top surface of the container filled with the resin material to form a curved surface part. SOLUTION: A coin type tag 1 has a substrate 2 where an LSI, a capacitor, etc., are packaged as the electronic parts and then the antenna coils 5 are connected to the substrate 2 to construct an intlet. The intlet is stored in a cup 7 serving as a container made of resin, and the cup 7 is filled with the fused resin 8 that is supplied through a top surface opening part of the cup 7 and then hardened. Then the outer fringe part of the top surface of the cup 7 is filed to form a curved surface part 9. Thus, the production of the tag 1 is over. In such a constitution, a commodity is never impaired when the tag 1 is attached to the commodity. |
