PROBLEM TO BE SOLVED: To improve moire and contrast unevenness by forming mesh of 10 μm or less in line width with conductive ink.SOLUTION: A see-through electrode member 10 includes a primer layer 2 having a projection flat portion 2f and a primer projection streak portion 2r on a transparent base material 1, and a conductive projection streak portion 3 in a mesh pattern 3P including conductive particles and a binder resin on the primer projection streak portion. Conductive mesh 4 comprises the primer projection streak portion and the conductive projection streak portion, and the conductive projection streak portion is such that a peak portion 3t of a conductive particle contact portion is equal to or larger than H/4 of a conductive mesh height H and a conductive mesh width Wt at H/4 is less than a foot width W4. The mesh pattern comprises a border segment L extending between branch points B to define an opening region A, a) the average number N of border segments extending from one branch point satisfying 3.0≤N<4.0, b) the opening region being in two or more kinds of a pentagonal, a hexagonal, and a heptagonal shape and the hexagonal shape being the most, and c) a polygonal shape having the same number of sides being indefinite. Further, d) the opening regions are arranged better not in a direction with periodicity. |
