A stretchable wiring board includes: a stretchable base; at least one stretchable wiring provided on the stretchable base; and a poorly stretchable member provided so as to overlap at least part of the stretchable wiring in a thickness direction looking at the stretchable base in planar view. The poorly stretchable member suppresses change in a resistance value of the stretchable wiring associated with stretching deformation of the stretchable base. As a result, stable operability can be secured without affecting an operating voltage of an electronic component.
