We investigated an effect of an elongation stiffness of a substrate and a metal wire to stretchability of a wavy metal wire. We focused on a ratio of the elongation stiffness of the substrate to that of the metal wire. In tensile test using two kinds of wavy specimens, most of the results showed increase of the maximum elongation at increase of the elongation stiffness ratio. When the elongation stiffness ratio is changed from 0 to 0.910, the stretchability is increased from 0.322 to 0.594 and from 0.337 to 0.425. This result suggests that stretchability can be improved by designing the elongation stiffness ratio.
