Stretchable mounting substrate

A stretchable mounting substrate comprising:

• a stretchable wiring substrate, wherein the stretchable wiring substrate includes a stretchable base material and a stretchable wiring arranged on the stretchable base material;
• and
• a module on a surface of the stretchable wiring substrate, wherein the module includes a multilayer substrate, a plurality of electronic components on a principal surface of the multilayer substrate, a plurality of first electrodes and a plurality of second electrodes on the principal surface of the multilayer substrate and electrically connected to the stretchable wiring substrate, and internal wirings inside the multilayer substrate,
• wherein the module has a first electrode arrangement region where the plurality of first electrodes are arranged and a second electrode arrangement region where the plurality of second electrodes are arranged,
• wherein an internal wiring of the internal wirings electrically connects a first electrode of the plurality of first electrodes and a second electrode of the plurality of second electrodes to form a node electrode pair, and
• wherein the internal wiring of the node electrode pair and the stretchable wiring on the stretchable base material intersect each other in plan view of the stretchable wiring substrate.
