Abstract
Provided is a stretchable circuit board including: a stretchable base material having stretchability; a film base material overlapping with part of a one-surface-side surface of the stretchable base material and having lower stretchability than that of the stretchable base material; a stretchable wiring line formed on the one-surface-side surface of the stretchable base material; and an adhesive layer formed on one surface side or the other surface side of the stretchable base material. The adhesive layer is formed on both of an overlapping region where the stretchable base material overlaps with the film base material and a non-overlapping region where the stretchable base material does not overlap with the film base material.

A stretchable circuit board comprising:
- a stretchable base material having stretchability;
- a film base material overlapping with part of a one-surface-side surface of the stretchable base material and having lower stretchability than that of the stretchable base material;
- a stretchable wiring line formed on the one-surface-side surface of the stretchable base material;
- and
- an adhesive layer formed on the one surface side or the other surface side of the stretchable base material,
- wherein the adhesive layer is formed on both of an overlapping region where the stretchable base material overlaps with the film base material and a non-overlapping region where the stretchable base material does not overlap with the film base material.
A method for manufacturing a stretchable circuit board, comprising steps of:
- A) forming a stretchable wiring line on a one-surface-side surface of a stretchable base material having stretchability;
- B) forming a film base material having lower stretchability than that of the stretchable base material such that the film base material overlaps with part of the stretchable base material;
- and
- C) forming, on the one surface side or the other surface side of the stretchable base material, an adhesive layer on both of an overlapping region where the stretchable base material overlaps with the film base material and a non-overlapping region where the stretchable base material does not overlap with the film base material.
