A stretchable circuit board includes a stretchable base, a stretchable wiring portion, a reinforcement base having in-plane rigidity higher than that of the stretchable base 10, and a draw-out wiring portion. The stretchable wiring portion having stretchability is formed on a main surface located on at least one side of the stretchable base. The draw-out wiring portion is formed at least on a main surface that is one side of the reinforcement base. The main surface of the reinforcement base is overlaid with a part of an area where the stretchable wiring portion is formed, in which the main surface faces the main surface of the stretchable base. A part of the stretchable wiring portion and a part of the draw-out wiring portion are joined together, and they are electrically continuous.
