In a photosensitive conductive paste containing photosensitive organic components, conductor powder, and quartz powder, melting of the quartz powder does not occur or is very unlikely to occur in a heat treatment step, and in the heat treatment step, it functions sufficiently to bring shrinkage rates and shrinkage behaviors of both of a conductor layer and an element body layer closer to each other when they shrink, and thus generation of voids can be inhibited when it is used for manufacturing a laminated coil component.
