A laminate member is provided which has excellent ion migration resistance between a light-sensitive resin layer and a conductive layer formed on a substrate. This laminate member is provided with a resin layer A formed on the substrate, a transparent electrode layer B formed on the resin layer A, and a conductive layer C formed on the resin layer A and the transparent electrode layer B, wherein the resin layer A contains a resin (a) containing a carboxyl group, the conductive layer C contains a resin (c) having conductive particles and a carboxylic group, the conductive layer C contacts the resin layer A and the transparent electrode layer B, and, defining Sas the acid value of an organic component contained by the resin layer A and Sthe acid value of an organic component contained by the resin layer C, the value of S&#x2212;Sis 20-150 mg KOH/g.

Laminate member and touch panel

Provided is a method for manufacturing a conductive pattern forming member that is formed on a substrate and that has excellent resistance to ion migration between a conductive pattern and a photosensitive resin layer, while suppressing generation of residues in the dissolution and removal of unexposed portions. This method for manufacturing a conductive pattern forming member includes: a coating step of applying, onto surfaces of a layer A formed of a resin (a) having a carboxyl group, and a transparent electrode layer B, the layers A and B being formed over a substrate, a composition C containing conductive particles and a resin (c) having a double bond and a carboxyl group to obtain a coating film C; a drying step of drying the coating film C to obtain a dry film C; an exposure step of exposing the dry film C to light to obtain an exposed film C; a developing step of developing the exposed film C to obtain a pattern C; and a curing step of curing the pattern C to obtain a conductive pattern C, wherein particles having a particle diameter of 0.3 to 2.0 &#x3bc;m account for 80% or more of the conductive particles.
