Abstract

A method for manufacturing a laminate containing patterned layers to be plated includes a step of preparing a laminate having a substrate having two main surfaces, and layers for forming a layer to be plated, respectively disposed on two main surfaces of the substrate and containing a polymerization initiator, a step of irradiating a layer for forming a layer to be plated in the laminate with light in a patternwise fashion under a predetermined requirement, and a step of removing non-light irradiated regions in the layers for forming a layer to be plated, thereby forming patterned layers to be plated on two main surfaces of the substrate. Also set forth are a touch panel sensor, a touch panel, a laminate containing patterned layers to be plated, and a metal layer-containing laminate.
