Touch panel
First Claim
1. A touch panel comprising:
- a light-transmissible upper board having an upper surface and a lower surface;
a lower board having an upper surface and a lower surface;
an upper resistor layer provided on the lower surface of the upper board;
a lower resistor layer provided on the upper surface of the lower board, the lower resistor layer facing the upper resistor layer with a predetermined space between the upper resistor layer and the lower resistor layer;
a wiring board having an upper surface, a lower surface opposite to the upper surface and an end, the end being located between the upper board and the lower board;
a plurality of wiring patterns provided on the lower surface of the wiring board, the plurality of wiring patterns being connected to the upper resistor layer and the lower resistor layer, respectively;
an insulating cover sheet provided on the wiring board, the cover sheet covering the plurality of wiring patterns and extending to an inside beyond an end of the lower board, the insulating cover sheet contacting the upper surface of the lower board; and
a first adhesive for allowing the upper board to adhere to the wiring board, the first adhesive being disposed on the upper surface of the wiring board.

Abstract
A touch panel includes a light-transmissible upper board, a lower board, an upper resistor layer on a lower surface of the upper board, a lower resistor layer provided on an upper surface of the lower board and facing the upper resistor layer with a predetermined space between the resistor layers, a wiring board having an end located between the upper board and the lower board, plural wiring patterns provided on the wiring board and connected to the upper resistor layer and the lower resistor layer, respectively, and an insulating cover sheet provided on the wiring board and covering the wiring patterns. The cover sheet extends to an inside beyond at least one of respective ends of the upper board and the lower board. This touch panel can be electrically connected to an electronic circuit stably.
