Abstract

The touch panel includes a light transmissive substrate, a first light transmissive conductive layer, and a second light transmissive conductive layer. The first conductive layer is provided on an upper surface of the substrate, and extending in a roughly band-shaped form in a first direction. The second conductive layer is provided on the upper surface of the substrate, insulated from the first conductive layer, and extending in a roughly band-shaped form in a second direction perpendicular to the first direction. The first conductive layers and the second conductive layers are plurally provided. The second conductive layer includes conductive parts provided on the upper surface of the substrate, and a connecting part provided for connecting the conductive parts in the second direction, and provided above the first conductive layer, and material of the connecting part is resin containing dispersed conductive fine wires.

Claims (19)

1 . A touch panel comprising:

a light transmissive substrate;

a first light transmissive conductive layer provided on an upper surface of the substrate, and extending in a roughly band-shaped form in a first direction; and

a second light transmissive conductive layer provided on the upper surface of the light transmissive substrate, insulated from the first light transmissive conductive layer, and extending in a roughly band-shaped form in a second direction perpendicular to the first direction, wherein

the first light transmissive conductive layer and the second light transmissive conductive layer are plurally provided, and

the second light transmissive conductive layer includes a plurality of conductive parts provided on the upper surface of the light transmissive substrate, and a connecting part provided for connecting the plurality of conductive parts in the second direction, and provided above the first light transmissive conductive layer, and material of the connecting part is resin containing dispersed conductive fine wires.

2 . The touch panel according to claim 1 , wherein

the first light transmissive conductive layer and the plurality of conductive parts are made of the same material and have the same film thickness.

3 . The touch panel according to claim 1 , wherein

an insulating layer is provided between the first light transmissive conductive layer and the connecting part.

4 . The touch panel according to claim 3 , wherein

a length of the connecting part in the first direction is shorter than a length of the insulating layer in the first direction.

5 . The touch panel according to claim 3 , wherein

a length of the connecting part in the second direction is longer than a length of the insulating layer in the second direction.

6 . The touch panel according to claim 3 , wherein

the insulating layer is provided on an upper surface of the plurality of conductive parts, and

the connecting part is connected to each of the plurality of conductive parts through an opening provided in the insulating layer.

7 . The touch panel according to claim 3 , wherein

the connecting part and the insulating layer are made of the same resin material.
