A touch sensor member includes a substrate sectioned into a display region and a design region; a conductive pattern formed on the display region and having a line width of 2 to 6 &#x3bc;m; and a conductive pattern formed on the design region and having a line width of 7 to 100 &#x3bc;m, wherein the conductive pattern having a line width of 2 to 6 &#x3bc;m and the conductive pattern having a line width of 7 to 100 &#x3bc;m have the same composition.

Method of producing touch sensor member, and touch sensor member

A method of producing a conductive pattern includes a light-exposing step of exposing a layer or pattern including conductive particles A, an organic compound B having an unsaturated double bond and a photopolymerization initiator C, and positioned over a substrate to light rays having a broad spectrum, to thereby produce a conductive layer or a conductive pattern.

Conductive pattern fabrication method

A photosensitive conductive paste contains conductive particles (A), a photosensitive organic compound (B), an epoxy resin (C) and an ion adsorbent (D) that is selected from the group consisting of hydrotalcite, magnesium oxide, aluminum oxide, aluminum hydroxide, magnesium hydroxide, magnesium carbonate, zirconium oxide, magnesium silicate, silicon dioxide, zeolite and a carbon-based powder.
