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. |
