MANUFACTURING METHOD OF CONDUCTIVE SUBSTRATE, CONDUCTIVE SUBSTRATE, STRETCHABLE WIRING SUBSTRATE, AND STRETCHABLE DEVICE

摘要

To provide a manufacturing method of a conductive substrate that includes a stretchable resin base material having a somewhat high tensile elastic modulus and that can manufacture a stretchable wiring substrate that is excellent in wiring stretchability.SOLUTION: There is disclosed a manufacturing method of a conductive substrate including a stretchable resin base material having a tensile elastic modulus of 10 to 50 MPa and a conductor layer provided on the stretchable resin base material. The disclosed method includes a step of forming a stretchable resin base material having the tensile elastic modulus of 10 MPa or more and less than 25 MPa such that the thickness is 40 μm or less, or a stretchable resin base material having the tensile elastic modulus of 25 MPa or more and 50 MPa or less such that the thickness is 25 μm or less, and a step of providing a conductor layer on the stretchable resin base material.SELECTED DRAWING: Figure 2
