Abstract: A wiring board includes a first substrate having stretchability, wiring disposed adjacent to a first surface of the first substrate and extending in a first direction, and a stopper disposed adjacent to the first surface or second surface of the first substrate. While stretch length of the wiring board is being increased in the first direction, electrical resistance of the wiring exhibits a first turning point at a first stretch length and tension applied to the wiring board exhibits a second turning point at a second stretch length smaller than the first stretch length. The first turning point is a point at which an increase in electrical resistance per unit stretch length changes. The second turning point is a point at which an increase in tension per unit stretch length changes.
