Abstract: According to an aspect, a stretchable device includes: a stretchable substrate extending in a planar direction; and a pair of stretchable resin layers with the stretchable substrate therebetween in a stacking direction. One of the stretchable resin layers has a surface. The surface has, when viewed in the stacking direction, a center region and a frame region surrounding the center region. The stretchable substrate includes a resin base member and an array layer disposed in the stacking direction. The resin base member includes a hinge meandering and extending in the planar direction. The hinge includes arcs formed in an arc shape when viewed in the stacking direction. The arcs have a center region arc disposed in the center region and a frame region arc disposed in the frame region. The radius of curvature of the frame region arc is smaller than that of the center region arc.
