1. An electrode member comprising:
a first electrode pattern and a second electrode pattern formed on a substrate such that the first electrode pattern and the second electrode pattern are disposed adjacent to each other with an insulation gap formed therebetween in a plan view from a direction normal to the substrate, the insulation gap extending in a longitudinal direction and having a width in a width direction perpendicular to the longitudinal direction,
wherein each of the first electrode pattern and the second electrode pattern has a same mesh-like pattern formed of a plurality of first thin metal wires extending in a first direction and a plurality of second thin metal wires extending in a second direction that intersects the first direction, both of the first direction and the second direction intersecting the longitudinal direction, the mesh-like pattern including a base pattern repeating along the first direction and the second direction,
wherein the insulation gap separates the second electrode pattern from the first electrode pattern, such that the base pattern in the second electrode pattern is shifted in the width direction with respect to the base pattern of the first electrode pattern,
wherein the first thin metal wires include first end wires each having a first end at an edge of the first electrode pattern or at an edge of the second electrode pattern along the insulation gap, such that each of the first end wires in the first electrode pattern and corresponding one of the first end wires in the second electrode pattern form a pair such that the respective first ends of the first end wires face each other across the insulation gap with a predetermined distance therebetween in the width direction,
wherein the second thin metal wires include second end wires each having a second end at the edge of the first electrode pattern or at the edge of the second electrode pattern along the insulation gap, such that each of the second end wires in the first electrode pattern and corresponding one of the second end wires in the second electrode pattern form a pair and face each other across the insulation gap with a predetermined distance therebetween in the width direction, and
wherein the pair of the first end wires and the pair of the second end wires do not extend into the insulation gap viewed from the longitudinal direction, the pair of the first end wires extending in the first direction in parallel to each other with a predetermined distance therebetween in a direction perpendicular to the first direction, and the pair of the second end wires extending in the second direction in parallel to each other with a predetermined distance therebetween in a direction perpendicular to the second direction.
