Conductive film and touch panel

A conductive film comprising a substrate, a first conductive part formed on one main surface of the substrate, and a second conductive part formed on another main surface of the substrate, wherein:

• the first conductive part contains two or more first conductive patterns composed of a thin metal wire;
• the first conductive patterns each contain a plurality of first pad portions connected by first connections;
• the second conductive part contains two or more second conductive patterns composed of a thin metal wire;
• the second conductive patterns each contain a plurality of second pad portions connected by second connections;
• the first pad portions each contain a first spiral extending from one of the first connections, a second spiral extending from an opposite first connection, and a first linkage for linking the first spiral and the second spiral;
• the second pad portions each contain a third spiral extending from one of the second connections, a fourth spiral extending from an opposite second connection, and a second linkage for linking the third spiral and the fourth spiral;
• the first spiral to the fourth spiral each contain a combination of a plurality of lattices;
• the first linkage and the second linkage each contain a plurality of conductive wires;
• and
• the first conductive patterns and the second conductive patterns are arranged such that the first linkage and the second linkage intersect in a substantially perpendicular manner.

A touch panel comprising a conductive film, which is used in a display panel of a display device, wherein:

• the conductive film contains a substrate and a conductive part formed on one main surface of the substrate;
• the conductive part contains two or more conductive patterns composed of a thin metal wire;
• the conductive patterns each contain a plurality of pad portions connected by connections;
• the pad portions each contain a first spiral extending from one of the connections, a second spiral extending from an opposite connection, and a linkage for linking the first spiral and the second spiral;
• the first spiral and the second spiral each contain a combination of a plurality of lattices;
• and
• the linkage contains a plurality of conductive wires.
