Abstract
The present invention relates to a highly contracted artificial fibroin fiber including a modified fibroin, in which a contraction percentage defined by the following equation exceeds 7%. Contraction percentage={1−(length of contracted artificial fibroin fiber/length of artificial fibroin fiber before being brought into contact with water after spinning)}×100(%)
