Wiring board and method for manufacturing wiring board

A wiring board, comprising:

• a substrate that is stretchable;
• a wiring positioned on a first surface side of the substrate, the wiring having a meandering shape section that includes peaks and valleys aligned along a first direction that is one of planar directions of the first surface of the substrate;
• a stretching control mechanism that controls extension and contraction of the substrate;
• and
• a support substrate that is positioned between the wiring and the first surface of the substrate, that has an elastic modulus greater than the elastic modulus of the substrate, and that supports the wiring, wherein
• the substrate has component regions and a wiring region adjacent to the component regions,
• the component regions include component-fixing regions and component-surrounding regions, each of the component-fixing regions overlapping a respective one of electronic components mounted on the wiring board when viewed along the normal direction of the first surface of the substrate, each of the component-surrounding regions being positioned around a respective one of the component-fixing regions,
• the stretching control mechanism is positioned in the component-surrounding region and at least includes a stretching control part that spreads to the border between the component-surrounding region and the component-fixing region,
• the wiring includes a first end connected one of the electronic components and a second end connected another one of the electronic components,
• the first end and the second end of the wiring overlap the support substrate and the substrate when viewed along the normal direction of the first surface,
• the periodicity of peaks and valleys on a second surface of the substrate positioned on the opposite side of the first surface is greater than the periodicity of peaks and valleys on the first surface of the substrate,
• the peaks and the valleys on the second surface appear in a section overlapping the meandering shape section, and
• the peaks and the valleys on the first surface appear in a section overlapping the meandering shape section.
