1. A stretchable device comprising:
a resin base member; and
an array layer stacked on the resin base member, wherein
the resin base member comprises:
a plurality of bodies disposed in a manner separated from each other; and
a plurality of hinges that couple the bodies,
each of the hinges includes a plurality of bends bending when viewed in a stacking direction in which the resin base member and the array layer are stacked,
each of the bends is divided into an inner peripheral portion positioned on an inner side and an outer peripheral portion positioned on an outer side with respect to a center serving as a boundary in a width direction intersecting a direction in which the bend extends,
a plurality of the inner peripheral portions included in one of the hinges constitute an inner peripheral region,
a plurality of the outer peripheral portions included in one of the hinges constitute an outer peripheral region,
the array layer includes a plurality of gauge lines overlapping the respective hinges when viewed in the stacking direction,
when viewed in the stacking direction:
one of the gauge lines overlaps the inner peripheral region of a corresponding one of the hinges without overlapping the outer peripheral region of the corresponding one of the hinges, or
one of the gauge lines overlaps the outer peripheral region of a corresponding one of the hinges without overlapping the inner peripheral region of the corresponding one of the hinges.
