Stretchable device

A stretchable device comprising:

• a stretchable first substrate that has a first main surface and a second main surface facing each other, the stretchable first substrate extending in a first direction;
• a stretchable first wiring on the first main surface and extending along the first main surface;
• a second substrate that has a third main surface and a fourth main surface facing each other;
• and a second wiring on the third main surface and extending along the third main surface, wherein the stretchable first substrate includes a connection region overlapping the second substrate and a non-connection region not overlapping the second substrate when viewed from a direction orthogonal to the first main surface, the stretchable first substrate and the second substrate are connected in the connection region, and the stretchable first substrate has a first hole portion in at least one of the first main surface and the second main surface in the non-connection region, wherein a shortest distance in the first direction between the first hole portion and the connection region is larger than a maximum diameter in the first direction of the first hole portion.
