Stretchable device

Abstract

According to an aspect, a stretchable device includes: a resin base member; an array layer provided to the resin base member; and a pair of resin layers that sandwich the resin base member and the array layer from both sides in a thickness direction in which the resin base member and the array layer are disposed, the resin layers being made of resin having lower elastic modulus than that of the resin base member. The resin base member includes: bodies separated from each other in a direction orthogonal to the thickness direction; and hinges coupling the bodies while meandering. The array layer includes functional elements overlapping the bodies when viewed in the thickness direction. The resin layers are provided with first rigid parts having higher elastic modulus than that of the resin that forms the resin layers. The first rigid parts overlap the bodies when viewed in the thickness direction.
