PROBLEM TO BE SOLVED: To provide a novel silk fiber that can overcome the drawbacks of existing silk.SOLUTION: The inventors construct a method to produce novel silk with modified elongation by hybridizing a fibroin gene derived from a Trichoptera insect (Hydropsyche angustipennis), and a fibroin gene derived from Bombyx mori, a lepidopteran insect, thus allowing a novel silk fiber to be provided.SELECTED DRAWING: None 【課題】本発明は、既存の絹糸の欠点を補い得る新規絹繊維を提供することをその課題とする。【解決手段】本発明は、毛翅目昆虫（トビケラ類）由来のフィブロン遺伝子と、鱗翅目昆虫であるカイコ由来のフィブロイン遺伝子をハイブリッドすることにより、伸度が改変された新規絹糸を生産する方法を構築し、新規絹繊維の提供を可能とした。【選択図】なし
