PROBLEM TO BE SOLVED: To provide a sealing device, with high reliability, capable of detecting that the device is opened by means of an IC tag.SOLUTION: A sealing key 100 includes: a container 111 including a body part 113 and an insertion part 112 inserted and fixed to a sealing device body; and an IC tag component where an IC chip 122, and a circuit pattern 123 connected to the IC chip 122 and including an antenna configuration for enabling non-contact communication with the IC chip 122, are formed on a base material 121. The IC tag component is fixed and stored in the container 111, the circuit pattern 123 is formed across the insertion part 112 and the body part 113, and separation facilitating process 124 is applied to a boundary between the insertion part 112 and the body part 113 on the base material 121. |
