Abstract

The present invention relates to a composition for forming a conductive pattern which is capable of forming a fine conductive pattern on a variety of polymeric resin products or resin layers by a simplified process, while imparting excellent flame retardancy to the resin products or resin layers, and a resin structure having the conductive pattern obtained using the composition. The composition for forming a conductive pattern includes: a polymer resin; a non-conductive metal compound including a first metal element and a second metal element, having a R 3 m or P6 3 /mmc space group in crystal structure; and a flame retardant, wherein a metal nucleus including the first metal element, the second metal element or an ion thereof is formed from the non-conductive metal compound by the electromagnetic irradiation.
