Abstract
Provided is a stretchable circuit board including: a stretchable base material having stretchability and including a stretchable wiring line on one main surface; an electrode formed on at least the main surface of the stretchable base material and connected to the stretchable wiring line; an adhesive layer directly or indirectly bonded to the main surface on which the electrode is formed and formed in a region of the main surface other than an electrode region including the electrode; and an adhesive layer separator detachably bonded to the adhesive layer and having an opening formed at a position corresponding to at least part of the electrode region.
Claims7
A stretchable circuit board comprising:
- a stretchable base material having stretchability and including a stretchable wiring line on one main surface;
- an electrode formed on at least the main surface of the stretchable base material and connected to the stretchable wiring line;
- an adhesive layer directly or indirectly bonded to the main surface on which the electrode is formed and formed in a region of the main surface other than an electrode region including the electrode;
- and
- an adhesive layer separator detachably bonded to the adhesive layer and having an opening formed at a position corresponding to at least part of the electrode region.
A method for manufacturing a stretchable circuit board, comprising, in a sequence set forth, steps of:
- A) detaching a first adhesive layer separator bonded to a first surface from an adhesive layer having the first adhesive layer separator and a second adhesive layer separator bonded to a back surface of the first surface and having an opening;
- and
- B) directly or indirectly bonding the adhesive layer to at least one main surface after the adhesive layer and a stretchable base material having an electrode formed on the at least one main surface and a stretchable wiring line formed connected to the electrode have been position-adjusted such that the opening corresponds to a position of the electrode.
