METHOD FOR PRODUCING SEALING KEY, SEALING KEY, AND SEALING DEVICE

摘要

This sealing key comprises: a container; and an IC tag component fixed inside the container. The container has a shape including: a body part; and an insertion part that protrudes from the body part. The IC tag component includes: a substrate; an IC chip mounted on the substrate; and a circuit pattern formed on the substrate. The circuit pattern includes an antenna structure that connects with the IC chip and that enables non-contact communication in the IC chip. This method for producing said sealing key comprises: arranging, in a mold, a support part that constitutes a portion of the container; arranging the IC tag component on the support part such that the circuit pattern is arranged at a position extending across the boundary between the insertion part and the body part; and pouring a resin into the mold, and thereby forming a resin seal part so as to be joined with the support part, the resin seal part constituting a portion of the container and sealing the IC tag component.
