Title:
CONDUCTIVE SHEET AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/065430
Kind Code:
A1
Abstract:
In a conductive sheet using a metal nanofiber, metal migration in a visible conductive pattern is eliminated. Also, the intervals of the conductive portion (separate sheet terminal) are shortened. On a substrate (26) is a conductive sheet (10), formed from a transparent conductive pattern (11) and a visible conductive pattern (16). The transparent conductive pattern comprises a first nanofiber layer (12) that is a layer including a metal nanofiber, and a first heat-insulating layer (29) adjacent to the first nanofiber layer. The visible conductive pattern (16) forms an underlayer pattern from a second nanofiber layer (17) that is a layer including a metal nanofiber, and a second heat-insulating layer (27) adjacent to the second nanofiber layer; and a top-layer pattern comprising a paste layer (18) that is a layer including a metal paste laminated on the underlayer pattern. The second heat-insulating layer (27) is a conductive sheet that is a layer including a metal nanofiber cut to a minimum size. The visible conductive pattern (16) forms a water-shielding layer (21) on the underlayer pattern, and forms the top-layer pattern on the water-shielding layer.
