First Claim
1. A wiring board including an insulating board and an electroconductive section disposed on a surface of the insulating board, whereinthe electroconductive section comprises:
- a plurality of electrodes disposed on the surface of the insulating board;
a plurality of terminals disposed on the surface of the insulating board in corresponding relation to the electrodes, for electric connection to an external circuit; and
terminal interconnects disposed on the surface of the insulating board and configured to electrically connect the electrodes respectively to the terminals corresponding thereto, said terminal interconnects are made of a single material;
a line width of a portion of each of the terminal interconnects which lies within a circle having a radius of 10 mm about a boundary between the terminal interconnect and the corresponding one of the terminals is configured to be 5 μ
m or greater and 100 μ
m or smaller; and
an interconnect resistance value of each of the terminal interconnects is configured to be 100 ohms or greater and 10 kohms or smaller, whereinthe plurality of electrodes are disposed as a transparent electroconductive layer on the surface of the insulating board;
the plurality of terminals are disposed on the surface of the insulating board in corresponding relation to the electrodes, for electric connection to an external circuit;
the terminal interconnects are disposed on the surface of the insulating board and configured to electrically connect the electrodes respectively to the terminals corresponding thereto; and
the electroconductive section has a same thickness in the electrodes, the terminals, and the terminal interconnects.

Abstract
A wiring board includes a plurality of first terminal parts for electrically connecting with a control circuit and disposed corresponding to a plurality of first electrode parts, and first terminal wiring parts for electrically connecting the plurality of first electrode parts and the corresponding first terminal parts. Each of the first terminal wiring parts has, in at least a portion thereof falling in a circle with a radius of 10 mm centering around a boundary part between the first terminal wiring parts and the corresponding first terminal parts, a portion having a line width of 5 μm to 100 μm inclusive, the wiring resistance value of the first terminal wiring parts connected to the first terminal parts being 100 ohms to 10 kohms inclusive.
