Abstract: According to an aspect, a stretchable device includes: a resin base member; and a signal line and a strain gauge stacked on the resin base member. The resin base member includes: a plurality of bodies disposed separately from each other; and a plurality of hinges that couple the bodies while meandering. The hinges each include: a plurality of bends that bend and are disposed between the bodies; and a base that linearly extends to couple one of the bodies to a corresponding one of the bends. The signal line includes: a bend signal line stacked on the bends; and a base signal line stacked on the base. The base signal line has an occupied area per unit length in a length direction of the signal line larger than the bend signal line when viewed in a stacking direction in which the signal line is stacked on the resin base member.
