Abstract
A laser beam type working apparatus and method are disclosed which join together metal conductors formed as an alternate layer structure over a surface side of a light-transmitting substrate with an interposing electrical insulator provided therebetween. The joining together of these metal conductors in achieved by directing a laser beam from a rear-surface side of the substrate to an underlying metal conductor to melt it so that it flows out upwardly in a molten state so that the underlying metal conductor is connected to an overlying metal conductor.
